CONTENTS.

[INTRODUCTION]

AS Mr. Woodbury stated in his introduction to the original edition of this book, in order to avoid misunderstanding, it would be well to explain at the outset that it is not intended as an instruction book in the art of photography in any sense of the word. It is assumed that the reader has already mastered the technical difficulties of photographic practice and is able to make a good negative or print.

It was the purpose of the author to describe a number of novel and curious effects that can be obtained by the aid of the camera, together with some instructive and interesting photographic experiments.

The contents of the work were compiled from various sources, chiefly from "The Photographic Times," "The Scientific American," "The American Annual of Photography," "La Nature," "Photographischer Zeitvertreib," by Herman Schnauss, and "Les Recreations Photographiques," by A. Bergeret et F. Drewin; and the illustrations were likewise taken from various sources.

In conclusion the author or compiler modestly lays claim to very little himself, quoting the words of Montaigne, who said:—

"I have gathered me a posie of other men's flowers, of which nothing but the thread that binds them is mine own."

And yet so popular did the book prove that in the course of its first ten years of life, it ran through edition after edition.

The publishers of "The Photographic Times" later acquired the copyright of the popular volume and published three editions.

The publishers of American Photography acquired the book during the Great War through their purchase of "The Photographic Times," but in spite of a steady demand for the book after the limited stock had been sold out, did not find it advisable to reprint it until now.

In putting the book to press at this time, most of the original plates have been used. A number of the old pictures have been replaced by more modern examples and 14 pages have been added to the book, including several new topics.

The publishers would be glad to receive manuscripts and pictures describing and illustrating novel and interesting photographic effects not mentioned in this volume, to be published in American Photography and incorporated in the next edition of Photographic Amusements. They also request that photographers who make photographs illustrating any of the topics treated in the book, and especially those illustrated by wood cuts, may submit them for consideration, as they are prepared to purchase such as may seem available for the next edition.

[PHOTOGRAPHIC AMUSEMENTS]

[THE MIRROR AND THE CAMERA.]

Quite a number of novel effects can be obtained by the aid of one or more mirrors. If two mirrors are taken and placed parallel to one another, and a person placed between, the effect obtained is as shown in Fig. 1, where one soldier appears as a whole regiment drawn up into line. To make this experiment we require two large-sized mirrors, and they must be so arranged that they do not reflect the camera and the photographer, but give only multiple images of the sitter. This will be found quite possible; all that is necessary is to make a few preliminary experiments, adjusting the mirrors at different angles until the desired effect is obtained.

FIG. 1.—EFFECT OBTAINED WITH PARALLEL MIRRORS.

A process of multiphotography which was at one time quite popular consisted in posing the sitter with his back to the camera as shown in Figs. 2 and 3. In front of him are arranged two mirrors, set at the desired angle to each other, their inner edges touching. In the illustrations here given the mirrors are inclined at an angle of 75 deg., and five reflected images are produced. When an exposure is made and the negative developed, we not only have the back view of the sitter but the full reflected images in profile and three-quarter positions as well.

FIG. 2.—DIAGRAM OF THE PRODUCTION OF FIVE VIEWS OF ONE SUBJECT BY MULTIPHOTOGRAPHY.

In the diagram, Fig. 2, reproduced from "The Scientific American" the course taken by the rays of light, determined by the law that the angle of incidence is equal to the angle of reflection, is plainly marked out. We see here their passage from the sitter to the mirror and back to the camera. Provided the mirror be large enough, images of the full length figure can be made as shown in Fig. 4.

For photographing articles where it is of advantage to secure a number of different views of the same object this method of photographing with mirrors opens up quite a wide field of possibilities. In France it is used for photographing criminals, and thus obtaining a number of different portraits with one exposure.

FIG. 3.—GALLERY ARRANGED FOR MULTIPHOTOGRAPHY.

The use of an ordinary mirror in portrait work has enabled photographers to produce very pleasing results. There is often a very striking difference between the full and side views of a person's face, and by means of such a combination as this, one is enabled to secure a perfect representation of both at the same time. In making reflection portraits it has often been noted that the reflection has a more pleasing effect than the direct portrait. The reason of this is that it is softer and the facial blemishes are not so distinctly brought out. There is naturally a slight loss of detail, but this is by no means a drawback. The worst fault of the camera in portrait photography is the tendency to include every little detail which the artist would suppress. It not only includes all the detail, but often exaggerates it to a painful extent. By making a portrait by reflection this defect is avoided. Of course the image is reversed, but this is in most cases of little consequence; in fact, the sitter himself would be more likely to consider it a far more truthful likeness, for when we look into a mirror we do not see ourselves as others see us, but a reversed image. With some faces the difference is quite striking.

FIG. 6.—ELONGATED REFLECTION IN A SPOON.

Very many amusing effects can be obtained by the use of a convex mirror. Even an ordinary, well-polished spoon may be made to give some curious results. (See Fig. 6.) The thin man becomes an elongated mass of humanity to whom Barnum would have given a big salary, while the fat man may be reduced to the proportions of a walking-stick.

Convex mirrors for producing these ludicrous effects can be purchased at any mirror manufacturer's store. The advantage of the camera lies in the ability to secure permanently the curious images produced.

Even more ridiculous-looking images can be secured by the use of a piece of uneven glass silvered. For a method of silvering glass we are indebted to the kindness of Dr. James H. Stebbins, Jr., the well-known analytical chemist. Dissolve pure nitrate of silver in distilled water in the proportion of 10 grains to 1 ounce, and add carefully, drop by drop, sufficient strong ammonia solution to just dissolve the brown precipitate at first formed, stirring constantly during the addition.

Make a solution of Rochelle salt, 1 grain to the ounce of distilled water. Clean the plate of glass thoroughly with a little wet rouge and polish dry with a piece of chamois leather. Warm it before the fire or in the sun to about 70 to 80 deg. Fahr., and lay it on a perfectly level surface. Then mix 1 ounce of the silver solution with half an ounce of the Rochelle salt solution and pour the mixture on the glass so that every part of the surface will be evenly covered with it.

FIG. 7.—CURIOUS EFFECT OBTAINED WITH A CONVEX MIRROR.

Allow this to stand in the warm sunshine from half to one hour, when the reduced silver will be deposited as a fine film over the surface of the glass. When this is done wash off the glass with distilled water and wipe the entire surface very gently with a little wet wadding, which will take off the roughness and render it easier to polish. When perfectly dry the silver should be polished by rubbing with some smooth, hard surface. The plate is then varnished by pouring over it a suitable varnish and is ready for use.

[THE PHOTO-ANAMORPHOSIS.]

The name anamorphosis has been given to two kinds of pictures distorted according to a certain law, and which are of such a grotesque appearance that it is often impossible to recognize the subject of them; while viewed with proper apparatus they appear as perfectly correct images. One kind is designed to be viewed by reflection and the other is reconstituted by means of a special rotary apparatus.

FIG. 8.—ANAMORPHOSIS VIEWED IN CONVEX CYLINDRICAL MIRROR.[1]

[1] From "Experimental Science." Published by Munn & Co., New York.

Until quite recently, these pictures were drawn approximately from the reflection of the object as seen in a convex mirror, the position of which was indicated on the drawing and which restored it to its real form. M. Fenant conceived the idea of employing photography for obtaining these pictures. Fig. 9 reproduces a photo-anamorphosis from a negative by M. Fenant. If a cylindrical mirror be placed on the black circle shown in the reproduction the photograph will appear in its original form. Our illustration represents a portrait, although the features are barely recognizable. Similar pictures may be obtained by photographing the drawing or subject reflected in a cylindrical concave mirror placed perpendicularly.

FIG. 9.—A PHOTO-ANAMORPHOSIS.

The second kind of anamorphosis is produced by the distortion of the picture in the sense of one of its dimensions. To reconstruct it, it is caused to rotate rapidly, at the same time that a disc, perforated with a slit through which the picture is viewed, is rotated in front of it at a slightly different speed.

The apparatus invented by M. Linde for producing the anamorphosis is shown in Figs. 10 and 11. G is a camera provided with a revolving plate-holder, T H are revolving discs the movement of which is made to bear a certain relation to that of the plate-holder by means of the band F and the pulleys D D. The whole is set in operation by a piece of clockwork and the cord F. A is the axis of the camera, B that of the plate-holder, and C that of the revolving disc. On this disc is fixed the picture from which it is desired to make an anamorphosis. The relative motions are so regulated that when the plate-holder has made a complete revolution the disc has turned through an angle of 60 to 80 degrees in the opposite direction. Between the plate-holder and the lens is a diaphragm pierced with a slit about 10 millimetres wide. The action of the light on the plate takes place through this slit. The negative obtained, prints are made upon plain salted paper and rendered transparent with wax or vaseline. These pictures can be viewed in the ordinary apparatus used for showing anamorphoses of this kind. The print is fastened to a revolving apparatus and in front of it is another disc painted black and provided with a number of slits. The latter revolves at one-fourth the speed of the picture, and the image when viewed through the slit resumes its normal proportions.

FIGS. 10 AND 11.—LINDE'S APPARATUS FOR PHOTO-ANAMORPHOSIS.

[STATUETTE PORTRAITS.]

These were at one time quite popular, and if properly managed can be rendered very effective. There are several methods of making this kind of picture. If the photographer possesses a pedestal large enough, all that is necessary is to place this on a stand and the person to be photographed is arranged behind.

FIG. 12.

The breast is uncovered and some white soft material artistically arranged in folds over the shoulders and in such a way as to appear connected with the pedestal. A black background is placed behind and the exposure made. To give a more realistic effect the hair, face, and all other parts showing should be liberally powdered over with a white powder or rice flour. The negative produced will have a clear glass background, but the body of the figure will still be visible. This is removed by cutting away the film round the pedestal and to the arms on each side, leaving only those parts remaining that are required to produce the statuette. In printing we get a white statuette portrait on a dark background.

If the photographer does not possess a pedestal, the next best means to produce these pictures is to get a large sheet of cardboard and cut it out to the shape shown in the figure beneath, and with white paint make the picture of a pedestal, shading with a little gray to give rotundity. The figure is stationed behind it, and a black background used.

A third method involves still less trouble. This is to purchase a ready made pedestal negative. These are film negatives of a pedestal that can be adjusted to the negative of the subject desired to be produced as a statue. After the negative is taken and varnished the film is scraped off round the figure, cutting off the body as shown in the first illustration, after which the pedestal negative is adjusted, fastened, and then printed. The negative is reversible and can also be used for different subjects. The picture shown in Fig. 13 was made by Mr. G. B. Bradshaw, of Beach House, Altrincham, England, by means of one of his pedestal negatives.

[MAGIC PHOTOGRAPHS.]

FIG. 14.—CIGARETTE TUBE FOR MAGIC PHOTOGRAPHS.

Take an ordinary silver print and fix it without toning. Thoroughly well wash it to remove all traces of the fixing solution and then immerse it in a saturated solution of bichloride of mercury, when the image will disappear. The bichloride of mercury changes the photograph into white chloride of silver and chloride of mercury which is also white. The image when on white paper is thus rendered invisible.

Next soak some strong bibulous paper in a saturated solution of sodium hyposulphite, and, when dry, paste a piece of the paper to the back of the invisible print with a little starch paste, attaching it by the edges only. Of course the image can also be made to appear by soaking the invisible print, without the bibulous paper attached, in a solution of sodium sulphite, hypo, or water with a little ammonia added.

FIG. 15.—DEVELOPING THE IMAGE.

Magic photographs made in the manner above described can also be developed by smoke. A novelty, introduced in Paris some time ago, consisted of a cigarette or cigar holder, shown in Fig. 14, containing in its stem a little chamber for the insertion of a small piece of apparently plain paper, but in reality an invisible photograph produced in the manner already described. The ammonia vapor in the smoke passing through the chamber attacked the print and developed the image. By blowing the smoke on the latent image it may be made to appear, but the operation is rather tedious, and anyone with a little ingenuity can easily construct a cigarette holder with an arrangement to hold small pictures and allow the smoke to pass through.

The chamber of the cigarette or cigar holder must of course be sufficiently large to allow of the print being inserted in such a manner that the smoke can readily attack its surface, otherwise uneven development of the image will take place.

[SPIRIT PHOTOGRAPHY.]

FIG. 16.—A "SPIRIT" PHOTOGRAPH.

Many years ago, in the old wet-collodion days, a well-known photographer was one day surprised by the visitation of a spirit. The apparition did not make its appearance during the nocturnal hours, as is, we have been given to understand, the custom of these ladies and gentlemen from the other world, but, strangely enough, in broad daylight; and not by his bedside to disturb his peaceful slumber, but upon the photograph he was in the act of producing. Had this gentleman been of that soft-brained kind, so easily gulled by the professional spiritualist, it is possible that he would not have done what he did, which was to make a thorough and scientific examination as to the probable cause of the phenomenon. The case was this: A gentleman sitter had been taken in the usual manner upon a collodion plate. Upon taking a positive print from the negative, he was surprised to find a dim white figure of a lady apparently hovering over the unconscious sitter. Upon examination of the negative, the image of the figure was also visible, but not so plainly as in the positive. The explanation of the whole matter was soon discovered. In those days glass was not so cheap as at present, and all old or spoilt negatives were cleaned off and freshly prepared with collodion for further use. In this case the glass had previously supported the negative image of a lady dressed in white. Some chemical action had evidently taken place between the image and the glass itself, turning the latter slightly yellow in some parts. This faint yellow image, although hardly visible in the negative, had, being of a non-actinic color, given quite a distinct image in the positive. The case was not an isolated one, as these spirit photographs, as they were called, often made their appearance when old negatives were cleaned and the glass used again. The precise action producing the image has never, we think, been satisfactorily explained. It could often be made more distinct by breathing on the glass. We do not know if any enterprising humbug ever took advantage of this method of producing spirit photographs to extort money from the unwary, but about ten years ago a work was published, entitled "Chronicles of the Photographs of Spiritual Beings and Phenomena Invisible to the Material Eye," by a Miss Houghton. In this a number of reproductions of photographs of "spirits" were given with a detailed explanation of how they were obtained and the difficulties attending their production, the "spirits" being apparently of very independent natures, only making their appearance when they felt so inclined. It is quite possible that a person entirely ignorant of photographic methods might be led into the belief that they were actually photographic images of the dead, but we fear that the book is hardly well enough written to deceive the experienced photographer. At certain and most unfortunate periods in the process employed, some of the plates had a convenient habit of slipping into the washing tank and there, according to the author, becoming utterly ruined; also we learn that many were ruined by being accidentally smudged by the photographer's finger. We should not, we fear, have a very high opinion of an operator who was in the constant habit of "smudging" negatives with his fingers so as to entirely spoil them, nor can we quite understand what brand of plates was used that "got spoiled by falling into the water."

FIG. 17.—SPIRIT PICTURE.

From La Nature.
FIG. 18.—SPIRIT PICTURE.

It is not difficult to explain how these pictures were produced. There are quite a number of methods. With a weak-minded sitter, over whom the operator had complete control, the matter would be in no wise a difficult one. It would then only be necessary for the spirit, suitably attired for the occasion, to appear for a few seconds behind the sitter during the exposure and be taken slightly out of focus, so as not to appear too corporeal.

If, however, the sitter be of another kind, anxious to discover how it was done and on the alert for any deceptive practices, the method described would be rather a risky one, as he might turn round suddenly at an inconvenient moment and detect the modus operandi. In such a case it becomes necessary to find some other method where it would not be requisite for the "spirit" to make its appearance during the presence of the sitter.

FIG. 19.—SPIRIT PICTURE
DISTURBED SLUMBER

The ghostly image can be prepared upon the plate, either before or after the exposure of the sitter. The method is this: In a darkened room the draped figure to represent the spirit is posed in a spirit-like attitude (whatever that may be) in front of a dark background with a suitable magnesium or other artificial light thrown upon the figure, which is then focused in the "fuzzy-type" style; or, better still, a fine piece of muslin gauze is placed close to the lens which gives a hazy, indistinct appearance to the image. The exposure is made and the latent image remains upon the sensitive plate, which is again used to photograph the sitter. Upon developing we get the two images, the "spirit" mixed up with the figure. The spirit should be as indistinct as possible, as it will then be less easy for the subject to dispute the statement that it is the spirit-form of his dead and gone relative. Some amount of discretion in this part of the performance must be used, we fancy, otherwise the same disaster might happen as did to a spiritualist some little time ago. An elderly gentleman had come for a seance, and, after some mysterious maneuvers, the gentleman was informed that the spirit of his mother was there. "Indeed!" replied the old gentleman, somewhat astonished. "What does she say?" "She says she will see you soon," informed the medium. "You are getting old now and must soon join her." "Quite right," replied the old gentleman; "I am going round to her house to tea to-night."—Total collapse of spiritualist.

FIG. 20.—PHOTOGRAPH OF "SPIRITS."

Fluorescent substances, such as bisulphate of quinine, can also be employed. This compound, although almost invisible to the eye, photographs nearly black. If a white piece of paper be painted with the substance, except on certain parts, the latter only will appear white in the picture.

FIG. 21.-PAINTING BY N. SICHEL.
From which the "Spirit" Photograph opposite was made.

We hope that it will not be inferred that we desire to explain how to deceive persons with regard to photographs of spirits, for this is not so; we only hope that they will be made merely for amusement, and if possible to expose persons who practice on the gullibility of inexperienced persons.

Fig. 20 is a reproduction of a "spirit" photograph made by a photographer, claiming to be a "spirit photographer," and to have the power to call these ladies and gentlemen from the "vasty deep" and make them impress their image upon the sensitive plate by the side of the portraits of their living relatives.

Fortunately, however, we were in this case able to expose this fraud. Mr. W. M. Murray, a prominent member of the Society of Amateur Photographers of New York, called our attention to the similarity between one of the "spirit" images and a portrait painting by Sichel, the artist.

A reproduction of the picture is given herewith, Fig. 21, and it will be seen at once that the spirit image is copied from it.

In a recent number of The Australian Photographic Journal we read of the following novel method of making so-called spirit photographs: "Take a negative of any supposed spirit that is to be represented, put it in the printing frame with the film side out; lay on the glass side a piece of platinotype paper with the sensitive side up; clamp in place the back of the printing frame and expose to the sun for half a minute. Now place in the printing frame the negative of another person to whom the spirit is to appear, and over it put the previously exposed sheet film side down; expose to the sun for two minutes until the image is faintly seen, then develop in the usual way and the blurred spirit photograph will appear faintly to one side or directly behind the distinct image. Sheets of paper with different ghost exposures can be prepared beforehand."

Spirit photographs might easily be made by means of Prof. Roentgen's well-known X-ray process of impressing an image upon a photographic dry-plate without uncovering the shutter. The process would however entail considerable expense and would necessitate the use of so much costly apparatus that we will content ourselves with the simple mention of the possibility.

[PHOTOGRAPHY FOR HOUSEHOLD DECORATION]

How few amateur photographers there are who thoroughly enter into the enjoyment of the art-science as a pastime. Many of these, perhaps, must be excused for the reason that they are ignorant of its capabilities. Indeed, how many there are who imagine that the art of photography consists in making negatives and, from these, prints—good, bad and indifferent. All the friends and relations are called into requisition "to be taken." At first they do not mind, thinking it a fine thing to have a portrait made for nothing; but when they see the result they very naturally object to be caricatured, and the amateur loses many a friend, and the maiden aunt leaves all her money to the home for stray cats. If he is a married man and delights in a happy, cosy home, neatly and artistically decorated, photography can be of very great assistance to him—how much, few realize. There are a thousand different ways in which it can be of use, and the photographer has always before him some permanent record of his travels and skill.

FIG. 22.

Let us take, for instance, the making of transparencies. These are very simply made. Any moderately rapid dry plate can be used for the purpose. Every amateur becomes possessed after a time of a large number of negatives, good, bad, and indifferent. Let him carefully go through these, selecting all the printable ones and the pictures that he most admires. From these, transparencies can be made, either by contact, or enlarged or reduced in the camera. Persons residing in cities often have a nicely furnished room utterly marred by an unsightly outlook. Perhaps a view of chimney pots and dirty back yards. In such a case all that is necessary is to fit in place of the lower panes some neat photographs on glass, backed with thin ground-glass. These can be puttied in or they can be fitted in neat brass frames and hung up against the windows.

The craze of the present day appears to be in the direction of bright and gaudy colors, except with the more highly cultivated, who recognize the artistic value of unobtrusive colors and delicate tints. A photograph, provided it is a good one, is always to be preferred to colored pictures unless the latter are by good artists. We once constructed with a half dozen of transparencies a very neat lamp shade. Some idea of it can be obtained from Fig. 23.

FIG. 23.

A brass frame is first constructed, and any wire worker will execute this so as to hold the six or eight pictures. The transparencies are made, cut down to the size and shape required and fitted in; then ground glass of the same size and shape is fitted, small brass tabs at the back being used to keep them in their places behind the transparency. The glasses should not fit too tightly in the brass frames or, on expanding by the heat, they will crack.

A hall lamp can be treated in the same way, the colored glass removed and photographic transparencies substituted. Photos on glass can in the same way be used for a variety of other purposes, such as fire screens, candle shades, etc.

Next look up your stock of prints, scraps, waste prints, etc.

Often from a large, spoilt picture you can get a neat little bit about a couple of inches square or less; look up all these and from them a photographic chess-board can be made. Our illustration in Fig. 24 is intended to show what is meant, although our artist has not been happy in the selection of his material to represent photographic views and portraits. First mark out a square the size you wish the chess-board to be. Divide it into sixty-four squares and draw a neat border round it. Thirty-two of the squares are then neatly pasted over with selected photographs as varied as possible in subjects. Sixteen are fitted one way and sixteen the other. Our illustration is incorrect in this respect. The sixteen pictures should be placed the right way on the sixteen squares nearest to each player. When the photographs have all been pasted on and dried the whole is sized and varnished. If, however, it is desired to preserve this photographic chess-board, and at the same time to use it frequently, a better plan is to cover over with a glass plate and bind all round the edges to prevent dust from entering.

FIG. 24.

In a similar way a neat card table can be manufactured. Fig. 25 is intended to illustrate the top of the table covered with photographs and protected by a glass plate.

A little consideration will no doubt give various other similar ideas to the reader.

Those who can work the carbon process successfully have it in their power to transfer photographs in various colors to all kinds of supports, to wood for instance. The panels of a door can be very considerably improved by the insertion of photographs on fine grain wood, varnished.

FIG. 25.

Pictures can in this manner be transferred to plates, china and ornaments of every description.

Various methods of printing on silk and various fabrics have from time to time been given. Perhaps the best for our purpose is the primuline process, as various colored images can be produced, with but little trouble, on all kinds of material. A description of the process will be found in another part of this work. (See Page [39].)

These the amateur can hand over to his better half or female relations, who with the natural feminine abilities will produce all sorts of pretty artistic articles for decorating the room.

We are well aware that we have by no means enumerated one half of the various means in which photography can be employed for decorating the house, but hope at least to have given the reader some idea of what its capabilities are.

[LEAF PRINTS.]

FIG. 26.—LEAF PRINT. BY T. GAFFIELD.

Nothing can exceed the beauty of form and structure of the leaves of different plants. Ruskin observes: "Leaves take all kinds of strange shapes, as if to invite us to examine them. Star-shaped, heart-shaped, spear-shaped, fretted, fringed, cleft, furrowed, serrated, sinuated; in whirls, in tufts, in spires, in wreaths; endlessly expressive, deceptive, fantastic, never the same, from footstalk to blossom, they seem perpetually to tempt our watchfulness and take delight in outstripping our wonder." Photography has placed in our hands a simple method of preserving facsimiles of their ever varying shapes that will last long after the leaf has died and crumbled to dust. Although the discovery of the darkening action of silver chloride when exposed to light was discovered by Scheele as far back as 1777, little was apparently known of the possibilities attending the discovery until 1839, when Fox Talbot read a paper on "A Method of Photogenic Drawing," in which he described various experiments that could be made with paper coated with this substance, and showed many pictures of leaves, ferns, and pieces of lace which he had obtained.

FIG. 27.—LEAF PRINT. BY T. GAFFIELD.

The illustrations which we reproduce herewith are reproductions from leaf prints made by Mr. Thomas Gaffield, who has made quite a study of this fascinating pastime. In a little work entitled "Photographic Leaf Prints," published in 1869, he describes his method. The leaves and ferns are first selected and pressed between the leaves of a book. They must not be dried, as in that state they do not so readily permit the light to pass through and the delicate structure of the leaf would not be reproduced. They should therefore only be pressed sufficiently to allow the excess of moisture to be extracted. A sheet of glass is put into the printing frame and the leaves artistically arranged. When the arrangement is satisfactory the leaves are attached to the glass with a little mucilage to prevent them from slipping out of their places. A sheet of sensitive paper, albumen, gaslight, or platinum is then inserted, the frame closed up and exposed to the light until a very dark print is obtained. The time required in printing must be found by practice; it will, of course, differ according to the intensity of the light. It is a good plan to employ an actinometer to judge the correct exposure. It is not possible to open the frame, as a double or blurred picture would result. The halves should be exposed sufficiently long to enable the light to penetrate through them and give a distinct image of the veins and structure.

When the printing is completed the paper is removed and toned and fixed in the usual manner. If platinotype or gaslight paper is used, this, of course, requires development. The resulting picture gives us a light impression of the leaves on a dark background, but if so desired, the print thus obtained can be used as a negative. It can be made transparent with wax or vaseline, and prints obtained from it giving a dark image on a white ground. It is difficult to say which picture is the more beautiful. We give illustrations of pictures of both kinds. (Figs. 26 and 27.)

Naturally enough, the beauty of these pictures lies in the careful selection and arrangement of the leaves. Those which are too thick should not be used. Delicate ones, showing all the veins by transmitted light, are the most suitable. They can be arranged artistically, in any shape or form. We prefer, however, a life-like arrangement to the construction of various shapes and designs.

[TO MAKE A PEN AND INK SKETCH FROM A PHOTOGRAPH.]

By the following method anyone can, without any knowledge of drawing, produce from a photograph a pen and ink sketch suitable for reproduction as an illustration. From the negative a silver print is made on albumen or gelatine or collodion paper. This is fixed without toning in a solution of hyposulphite of soda. It must then be thoroughly washed to remove all traces of hypo, and when dry, the outlines of the photograph are traced over with a fine pen and a waterproof ink, obtainable at any artist's material store. If the photographer possesses a little knowledge of drawing, some of the shading can also be attempted. When the ink is dry the picture is immersed in a saturated solution of bichloride of mercury (poison) when the photograph will disappear, leaving the outline sketch intact. The picture is again well washed and dried. Newspaper sketches are often made from photographs in this manner, a zincotype being quickly produced from the drawing. Gaslight paper can also be used.

[PHOTOGRAPHS ON SILK.]

Photographs can be very effectively printed upon silk, satin, or other fabrics. There are several methods of accomplishing this. A simple one is the following:[2] The silk best suited for the purpose is that known as Chinese silk, and this is first washed in warm water with plentiful lather of soap, then rinse in hot water, and gradually cool until the final washing water is quite cold. Next prepare the following solutions: Tannin, 4 parts; distilled water, 100 parts. Sodium chloride, 4 parts; arrowroot, 4 parts; acetic acid, 12 parts; distilled water, 100 parts.

[2] From the "Encyclopaedic Dictionary of Photography," by the author.

The arrowroot is mixed up into a paste with a little of the distilled water, and the remainder added boiling hot, with the acid and the salt previously dissolved in it. When the solution is quite clear the tannin solution is added, and the whole allowed to get fairly cool. The silk is then immersed for about three minutes, being kept under without air in the folds, and then hung up to dry, or stretched out with pins on a flat board. The material is then sensitized by brushing over with the following solution: Silver nitrate, 12 parts; distilled water, 100 parts; nitric acid, 2 drops to every 3 ounces. Other methods of sensitizing are by immersing in or floating on the silver solution. After sensitizing, the material is dried by pinning on to a board to keep flat. It is then cut up as required, and printed behind the negative. Every care must be taken in printing to keep the material flat, and without wrinkles or folds. It must also be kept quite straight; otherwise, the image will be distorted. Printing is carried on in the same manner as with printing-out paper. It is then washed and toned in any toning bath. The sulphocyanide gives the best action. Fix in a 10 per cent. solution of hyposulphite of soda for ten minutes; wash and dry spontaneously. When just damp, it is ironed out flat with a not over-heated iron. Black tones can be obtained with a platinum toning bath, or with the uranium and gold toning bath, made up as follows: Gold chloride, 1 part; uranium nitrate, 1 part. Dissolved and neutralized with sodium carbonate, and then added to sodium chloride, 16 parts; sodium acetate, 16 parts; sodium phosphate, 16 parts; distilled water, 4,000 parts.

Very effective results may be made by printing with wide white margins, obtained by exposing with a non-actinic mask.

Another method is the following: Ammonium chloride, 100 grains; Iceland moss, 60 grains; water (boiling), 20 ounces.

When nearly cold this is filtered, and the silk immersed in it for about fifteen minutes. To sensitize, immerse the silk in a 20 grain solution of silver nitrate for about sixteen minutes. The silver solution should be rather acid.

Or immerse the silk in water, 1 ounce; sodium chloride, 5 grains; gelatine, 5 grains. When dry, float for thirty seconds on a 50 grain solution of silver nitrate. Dry, slightly overprint and tone in the following bath: Gold chloride, 4 grains; sodium acetate, 2 drachms; water, 29 ounces. Keep twenty-four hours before using. Fix for twenty minutes in hypo, 4 ounces to the pint of water.

[PHOTOGRAPHING A CATASTROPHE.]

On this page we reproduce a curious photograph by M. Bracq, which appeared some time ago in the Photo Gazette.

By M. Bracq. From Photo Gazette.
FIG. 28.—A CATASTROPHE.

Despite all the terrible catastrophe which it represents, carrying pictures along with him in his fall, the subject has not experienced the least uneasiness, not even so much as will certainly be felt by our readers at the sight of the tumble represented.

The mode of operating in this case is very simple and we are indebted to La Nature for the description of the method employed by M. Bracq. The photographic apparatus being suspended at a few yards from the floor of the room, in such a way as to render the ground-glass horizontal (say between the two sides of a double ladder—a combination that permits of easy focusing and putting the plates in place), there is spread upon the floor a piece of wall paper, about 6 feet in length by 5 feet in width, at the bottom of which a wainscot has been drawn. A ladder, a few pictures, a statuette, and a bottle are so arranged as to give an observer the illusion of the wall of a room, that of a dining room for instance. A hammer, some nails, etc., are placed at the proper points. Finally, a 5 feet by 2-1/2 feet board, to which a piece of carpet, a cardboard plate, etc., have been attached, is placed under the foot of a chair, which then seems to rest upon this false floor at right angles with that of the room.

FIG. 29.

Everything being ready, the operator lies down quietly in the midst of these objects, assumes a frightened expression, and waits until the shutter announces to him that he can leave his not very painful position. This evidently is merely an example that our readers will be able to modify and vary at their will.

[PHOTOGRAPHS ON VARIOUS FABRICS.]

By means of a dye process known as the "Primuline Process," very pretty images in various colored dyes can be made upon silks, satins, cotton goods, etc. The material is first dyed in a hot solution of primuline, made by adding about 15 to 30 grains of the dye to a gallon of hot water; a little common salt should also be added. On immersing the fabric, and stirring it about in the solution, it becomes of a primrose yellow color, when it is removed and washed under a cold-water tap. The next process is to diazotize it by immersion for half a minute or so in a cold solution of sodium nitrate, one-quarter per cent., which has been sharply acidified with hydrochloric or other acid. The material is again washed in cold water, but it must be kept in a weak light. It can be hung up to dry, in the dark, or exposed while wet beneath the object of which it is required to produce a positive reproduction. This process gives a positive from a positive, so that any ordinary picture on a sufficiently translucent material—flowers, ferns, etc.—can be reproduced. Printing requires about half a minute in the direct sunlight to half an hour or more in dull weather, or if the material to be printed through is not very transparent. The high lights become of a pale yellow, so that a faint image is perceptible; but this is made visible in almost any color by development in a weak solution (about one-fourth per cent.) of a suitable phenol or amine. The following have been found suitable:

For Red.—An alkaline solution of β-napthol.

For Maroon.—An alkaline solution of β-napthol-disulphonic acid.

For Yellow.—An alkaline solution of phenol.

For Orange.—An alkaline solution of resorcin.

Brown.—A slightly alkaline solution of pyrogallol, or a solution of phenylene-diamine-hydrochloride.

For Purple.—A solution of α-napthylamine hydrochloride.

For Blue.—A slightly acid solution of amido-β-napthol-sulphonate of sodium, now better known as "eikonogen."

If the design is to be made in several colors, this can be done by painting on the different developers, suitably thickened with starch. After developing, the material is well washed and dried. With the purple and blue developers it is necessary to wash the material finally in a weak solution of tartaric acid. Wool and silk require a longer exposure to light than other fabrics, and cannot be successfully developed with the maroon or blue developer.

FIG. 31.

Silhouette portraits were at one time very popular. They are simply made, and if the effect is well carried out will afford considerable amusement. The best description of their manufacture was given some time ago by Herr E. Sturmann, in Die Photographische Korrespondenz. His method is as follows:

Place two dark backgrounds in parallel position about 4 feet from the sky and side light of the studio and distant from each other about six feet. Improvise a dark tunnel by drawing a black cloth, of non-reflecting material, over the two dark grounds, and arrange a white screen, somewhat larger than the distance between the two dark grounds, in an oblique position so as to be fully illuminated.

The subject to be silhouetted must be placed in the centre of the tunnel, one side of the face turned towards one ground, but comparatively nearer to the white screen so that the side of the face turned towards the camera is as much as possible in the shade.

FIG. 32.

Focus must be taken accurately, so that the outlines of the figure are perfectly sharp.

As it is the object to obtain a perfectly transparent, glass-clear silhouette upon an absolutely opaque ground, but a very short time of exposure is required.

Develop as usual and to secure perfect opacity intensify more than usual. Plates of lower sensitiveness invariably give the best results. A slow plate or one made particularly for reproduction is well adapted for this kind of work. With ferrous oxalate or hydrochinon developer there is scarcely any need of intensifying.

FIG. 33.

FIG. 34.

To obviate the shadows cast upon the floor by the lower parts of the figure, place it upon a thick, large plate-glass, supported by props of five or six inches in height, and spread upon the floor under the glass a piece of white muslin. The muslin must be free of folds or wrinkles, and be so connected with the white screen, that the division line between is not reproduced upon the plate.

The very feeble shadows of the feet can be easily touched away with pencil.

Single persons or groups of two or three figures can be photographed in this peculiar style with very good effect.

For heads and busts expose in the usual manner, but to obtain silhouettes similar to those our grandmothers had cut in black paper, and long before photography was thought of, cut an appropriate mask of black paper to cover the part not wanted during printing.

FIG. 35.

It should be borne in mind that in this class of work the white background only is the object to be photographed, hence the necessity of but very short exposures. With longer exposures absolute blacks and whites are impossible.

[PHOTOGRAPHING THE INVISIBLE.]

The following is a curious and interesting experiment, based upon the peculiar property possessed by fluorescent substances of altering the refrangibility of the chemical light rays. Take a colorless solution of bisulphate of quinine, and write or draw with it on a piece of white paper. When dry the writing or design will be invisible, but a photograph made of it will show them very nearly black.

[HOW TO MAKE A PHOTOGRAPH INSIDE A BOTTLE.]

Get a glass-blower to make an ordinary shaped wine-bottle of very thin and clear glass, and clean it well. Next take the white of two eggs and add to it 29 grains of ammonium chloride dissolved in 1 drachm of spirits of wine, and one-half ounce of water. Beat this mixture into a thick froth and then allow it to stand and settle. Filter through a tuft of cotton-wool, and pour into the specially made bottle. By twisting the bottle round, an even layer of the solution will deposit itself on the sides. Pour off the remaining solution, allow the film in the bottle to dry, and again repeat the operation.

The next operation is to sensitize the film with a solution of nitrate of silver, 40 grains to 1 ounce of water. Pour this in and turn the bottle round for a few minutes, then pour off the superfluous solution and again dry. Hold the neck of the bottle for a few seconds over another bottle containing ammonia, so as to allow the fumes to enter it. Printing is the next operation; this is accomplished by tying a film negative round the bottle, and covering up all the other parts from the light. Print very deeply, keeping the bottle turning round all the time. Toning, fixing, and washing can be done in the ordinary way by filling the bottle up with the different solutions. The effect is very curious, and can be improved by coating the inside of the bottle with white enamel.

[PHOTOGRAPHS IN ANY COLOR.]

These can be produced by what is known as the powder or dusting-on process. The principle of the process is this: An organic, tacky substance is sensitized with potassium bichromate, and exposed under a reversed positive to the action of light. All the parts acted upon become hard, the stickiness disappearing according to the strength of the light action, while those parts protected by the darker parts of the positive retain their adhesiveness. If a colored powder be dusted over, it will be understood that it will adhere to the sticky parts only, forming a complete reproduction of the positive printed form. Prepare—Dextrine, one-half ounce; grape sugar, one-half ounce; bichromate of potash, one-half ounce; water, one-half pint: or saturated solution bichromate of ammonia, 5 drachms; honey, 3 drachms; albumen, 3 drachms; distilled water, 20 to 30 drachms.

Filter, and coat clean glass plates with this solution, and dry with a gentle heat over a spirit lamp. While still warm the plate is exposed under a positive transparency for from two to five minutes in sunlight, or from ten to twenty minutes in diffused light. On removing from the printing frame, the plate is laid for a few minutes in the dark in a damp place to absorb a little moisture. The next process is the dusting on. For a black image Siberian graphite is used, spread over with a soft flat brush. Any colored powder can be used, giving images in different colors. When fully developed the excess of powder is dusted off and the film coated with collodion. It is then well washed to remove the bichromate salt. The film can, if desired, be detached and transferred to ivory, wood, or any other support.

If a black support be used, a ferrotype plate on Japanned wood, for instance, pictures can be made from a negative, but in this case a light colored powder must be used. The Japanese have lately succeeded in making some very beautiful pictures in this manner. Wood is coated over with that black enamel for which they are so famous, and pictures made upon it in this manner. They use a gold or silver powder.

With this process an almost endless variety of effects can be obtained. For instance, luminous powder can be employed and an image produced which is visible in the dark.

Some time ago we suggested a plan of making what might be termed "post-mortem" photographs of cremated friends and relations. A plate is prepared from a negative of the dead person in the manner described, and the ashes dusted over. They will adhere to the parts unexposed to light, and a portrait is obtained composed entirely of the person it represents, or rather what is left of him. The idea is not particularly a brilliant one, nor do we desire to claim any credit for it, but we give it here for the benefit of those morbid individuals who delight in sensationalism, and who purchase and treasure up pieces of the rope used by the hangman.

[THE DISAPPEARING PHOTOGRAPH.]

A method of making a photograph which can be made to appear at will is thus described in Les Recreations Photographiques.

Take a convex watch crystal, V, or any similar larger glass if desired—for instance, those used for colored photographs; clean the glass well, place it perfectly level, convex side down, and fill it even full with a mixture of white wax and hog's lard. When it has solidified, apply to the back a flat glass plate, P, cut exactly to the largest dimensions of the convex glass, secure the glasses together with a strip, B, of gold-beater's skin, fastened by strong glue as shown in the figure. Now mount a portrait, with the front towards the convex glass, on the plate P. The combination is now ready; by heating it the wax between the two glasses melts and becomes transparent, allowing the portrait to be seen; on cooling it will lose its transparence and the portrait will disappear.

FIG. 36.

[FREAK PICTURES WITH A BLACK BACKGROUND.]

If an object be placed against a non-actinic background and an exposure made, the black parts surrounding it will not have any effect upon the plate, and the object can be shifted to another part and another exposure made. In a recent article published in La Nature, and translated in the Scientific American, a number of curious effects obtained by photography by M. R. Riccart, of Sainte-Foix-les-Lyons, are described and illustrated.

FIG. 37.—A DECAPITATION.

The system employed by the author of these photographs is that of the natural black background obtained through the open door of a dark room, combined with diaphragms skillfully arranged in the interior of the apparatus, between the objective and sensitized plate. This is the surest method of obtaining the desired effect with the greatest precision, without the junctions being visible, and with perfect sharpness in the cutting of the parts removed. For this effect, it is necessary to place the diaphragm at three or four centimeters from the ground glass, in the last folds of the bellows of the camera.

FIG. 38.—ANOTHER DECAPITATION.

The following are a few data as to the manner in which the scenes that we reproduce were obtained. The first, representing a decapitation by means of a saber (Fig. 37), was taken by means of an exposure in which the head was placed upon the block, the subject inclining forward upon his knees, and a diaphragm, occupying about two-thirds of the plate, completely masking the body up to the neck. Then, without changing the position of the apparatus, the diaphragm was placed on the other side in order to conceal the head, and the body was photographed in the second position along with the person representing the executioner. It would have been possible, by a third exposure, to so arrange things as to make the executioner the decapitated person. It was by the same process that the three following scenes were obtained: A person with his head placed before him in a plate (Fig. 38); a man carrying his head in a wheelbarrow (Fig. 39); and a person to whom his own head is served in a plate (Fig. 40). Such scenes may be varied to any extent. Fig. 41 is a photograph of a decapitation, while Fig. 42 is made by two exposures of an individual at different distances but so combined as to give the appearance of one exposure. Fig. 43 is that of a person in a bottle. The individual represented was first photographed on a sufficiently reduced scale to allow him to enter the bottle. This exposure was by using a screen containing an aperture, as for the Russian background. But this precaution was taken merely to conceal the floor, and yet it would perhaps be preferable in such a case to have the subject stand upon a stool covered with a very black fabric. However this may be, when once the first impression has been made, there is nothing more to be done than to photograph the bottle on a larger scale and the result is obtained.

FIG. 39.—THE HEAD IN THE WHEELBARROW

FIG. 40.—THE HEAD UPON A PLATE.

[HOW TO COPY DRAWINGS.]

There are three principal methods of copying mechanical drawings, tracings, sketches, etc. These are: (1) A process to obtain white lines upon a blue ground; (2) a process by which blue lines upon a white ground are obtained; and (3) a process giving black or violet-black lines upon a white ground.

FIG. 41.—THE SAWED-OFF HEAD.

The first process is undoubtedly the simplest, as after printing upon the paper it is developed and fixed by simple immersion in cold water; but, at the same time, the white lines on the blue ground are not so clear and effective as the other processes. The cyanotype paper, as it is called, can be obtained ready for use at any draughtsman's stores, but if you prefer to make it yourself, here is the recipe: Two solutions are made—20 parts of red prussiate of potash are dissolved in 100 parts of water, and 10 parts of ammonio-citrate of iron in 60 parts of water. These two solutions should be mixed together immediately before using, and the operation must be performed in the dark. Paper is floated on this solution, or applied with a broad camels-hair brush, and hung up to dry. If it is well dried and carefully preserved from light, moisture and air, this paper will keep for some time. After printing—which, when sufficient, should show the lines copied of a yellow color upon a blue ground—the prints should be washed in several waters, and if a few drops of chlorine water or dilute hydrochloric acid be added to the washing water, the blue ground will appear much darker and the lines rendered clearer and whiter. The commercial paper sold is generally prepared by this method.

FIG. 42.—THE REDUCTION.

FIG. 43.—MAN IN A BOTTLE.

Blue prints may be given a black tone by plunging them into a solution of 4 parts of caustic potash in 100 parts of water; then, when the blue color has entirely disappeared under the action of the potash, and a yellowish color has taken its place, they are immersed in a solution of 4 parts of tannin in 100 parts of water; then washing them again, we obtain prints whose tone may be assimilated to that of pale writing ink.

In the process giving blue lines upon a white ground, it is necessary that the action of the light shall be to convert the iron compound into one that can be discharged from instead of being fixed on the paper, so that we obtain a positive from a positive. Abney describes the process as follows: Thirty volumes of gum solution (water 5 parts, gum 1 part) are mixed with 8 volumes of a citrate of iron and ammonia solution (water 2 parts, double citrate 1 part), and to this is added 5 volumes of a solution of ferric chloride (water 2 parts, ferric chloride 1 part). This solution thus formed is limpid at first, but will gradually become thicker, and should be used soon after mixing. It is then applied with a brush to the paper (which should be well sized) and dried in the dark. Exposure is accomplished in a few minutes, the paper being placed under the drawing in the printing frame. It is then developed with potassium ferrocyanide, 50 grains, water 1 ounce, applied with a brush until all the details appear of a dark-blue color. The print is then rapidly rinsed, and placed in a dish containing the clearing solution, made of 1 ounce of hydrochloric acid and 10 ounces of water.

The third process, which gives violet-black lines on a white ground, is the following: Make up the sensitive solution with water, 16 ounces; gelatine, 4 drachms; perchloride of iron (in a syrup condition), 1 ounce; tartaric acid, 1 ounce; sulphate of iron, 4 drachms. The paper is floated on or brushed over with this and dried. The exposure is about the same as with the last process. When sufficient, the greenish-yellow color will turn white, except the lines, which should be somewhat dark. The developing solution is composed of 1 part of gallic acid in 10 parts of alcohol and 50 of water. When immersed in this solution the lines will turn blacker. The finish is then made by thoroughly washing in water.

[SYMPATHETIC PHOTOGRAPHS.]

These are obtained as follows: A sheet of paper is coated with a ten per cent solution of gelatine, and when dry this is floated on a ten per cent solution of bichromate of potash. Again dry and expose beneath a positive transparency. The print thus obtained is then immersed in a ten per cent solution of chloride of cobalt. The parts unacted upon by light will absorb the solution. Wash and dry. We then have a faint image which will alter its color according to the state of the atmosphere. In damp weather it will be almost if not entirely invisible, but when the weather is fine and dry, or if the image be heated before a fire it will turn to a bright blue color.

[DRY-PLATES THAT WILL DEVELOP WITH WATER.]

Some time ago dry-plates were placed on the market which would develop, apparently, with water and a little ammonia only. The secret of the method was that the backs of the plates were coated with a soluble gum, containing the developing agents, and, of course, when the plate was immersed in the water, they instantly dissolved and formed the developer. Plates thus prepared are useful in traveling where it is not always possible to get the necessary developing solutions. To prepare them the backs are coated with the following mixture:

This is allowed to dry at an ordinary temperature. After exposure, all that is necessary to develop is to immerse the plates in water containing a small quantity of ammonia.

[CARICATURE PHOTOGRAPHS.]

There are quite a number of different methods of making caricature portraits. A simple one is to make two photographs of an individual, one of the head alone and another of the entire body on a much smaller scale. From these two negatives prints are made, and the larger head is cut out and pasted on the shoulders of the full length figure. Any signs of the cutting out are removed by the use of a brush and a little coloring matter. From this combined print another negative is made so that any number of these caricature prints can be made without extra trouble. The effect is shown in Fig. 44.

From Tissandier's Handbook. FIG. 44.—CARICATURE PORTRAIT.

Foregrounds for making caricature portraits are sold in this country. The method of using them is shown in Fig. 45. The card containing the grotesque drawing is held by the sitter on his knees and arranged by the photographer in such a way that his head rests just above the neck of the painted body. A white background is arranged behind and when the negative is made all traces of the edges of the foreground are removed by careful re-touching.

FIG. 45.—CARICATURE

FIG. 46.—MAKING THE CARICATURE PORTRAIT.

Another method of obtaining grotesque caricature portraits has been devised by M. Ducos du Hauron. His apparatus, which he calls "La Photographie Transformiste," is thus described by Schnauss in his "Photographic Pastimes." A, Fig. 47, is the front of the box, which is furnished with an exposing shutter formed of a simple sliding piece fitting into the grooves R R, R R. B P are two screens pierced with slits a a, c c. C is the rear end of the box where the dark slide is placed. D is the lid of the box, which is lifted either for placing the slotted screens or for putting in the sensitive plate. When not working direct from nature, the transparency is placed in the grooves R R, R R, at A.
