It would not have been easy to give her a harsh one after reading her chosen maxim. "The Moment of Parting" was twice noticed. "The Haunted Spring", "Dearest May", "The Bony Boat", "Yankee Girls", "Yankee Ship and Yankee Crew", "My Country, 'tis of thee", and—was there ever anybody that ever broke up prose into lengths who would not look to see if there were not a copy of some performance of his own on the wall he was examining, if he were exploring the inner chamber of a freshly opened pyramid?
We left the great manufacturing establishment of the Messrs. Anthony, more than ever impressed with the vast accession of happiness which has come to mankind through this art, which has spread itself as widely as civilization. The photographer can procure every article needed for his work at moderate cost and in quantities suited to his wants. His prices have consequently come down to such a point that pauperism itself need hardly shrink from the outlay required for a family portrait-gallery. The "tin-types," as the small miniatures are called,—stanno-types would be the proper name,—are furnished at the rate of two cents each! A portrait such as Isabey could not paint for a Marshal of France,—a likeness such as Malbone could not make of a President's Lady, to be had for two coppers,—a dozen chefs d'oeuvre for a quarter of a dollar!
We had been for a long time meditating a devotion of a part of what is left of our more or less youthful energies to acquiring practical knowledge of the photographic art. The auspicious moment came at last, and we entered ourselves as the temporary apprentice of Mr. J.W. Black of this city, well known as a most skilful photographer and a friendly assistant of beginners in the art.
We consider ourselves at this present time competent to set up a photographic ambulance or to hang out a sign in any modest country town. We should, no doubt, over-time and under-tone, and otherwise wrong the countenances of some of our sitters; but we should get the knack in a week or two, and if Baron Wenzel owned to having spoiled a hat-full of eyes before he had fairly learned how to operate for cataract, we need not think too much of libelling a few village physiognomies before considering ourselves fit to take the minister and his deacons. After years of practice there is always something to learn, but every one is surprised to find how little time is required for the acquisition of skill enough to make a passable negative and print a tolerable picture. We could not help learning, with the aid that was afforded us by Mr. Black and his assistants, who were all so very courteous and pleasant, that, as a token of gratitude, we offered to take photographs of any of them who would sit to us for that purpose. Every stage of the process, from preparing a plate to mounting a finished sun-print, we have taught our hands to perform, and can therefore speak with a certain authority to those who wish to learn the way of working with the sunbeam.
Notwithstanding the fact that the process of making a photographic picture is detailed in a great many books,—nay, although we have given a brief account of the principal stages of it in one of our former articles, we are going to take the reader into the sanctuary of the art with us, and ask him to assist, in the French sense of the word, while we make a photograph,—say, rather, while the mysterious forces which we place in condition to act work that miracle for us.
We are in a room lighted through a roof of ground glass, its walls covered with blue paper to avoid reflection. A camera mounted on an adjustable stand is before us. We will fasten this picture, which we are going to copy, against the wall. Now we will place the camera opposite to it, and bring it into focus so as to give a clear image on the square of ground glass in the interior of the instrument. If the image is too large, we push the camera back; if too small, push it up towards the picture and focus again. The image is wrong side up, as we see; but if we take the trouble to reverse the picture we are copying, it will appear in its proper position in the camera. Having got an image of the right size, and perfectly sharp, we will prepare a sensitive plate, which shall be placed exactly where the ground glass now is, so that this same image shall be printed on it.
For this purpose we must quit the warm precincts of the cheerful day, and go into the narrow den where the deeds of darkness are done. Its dimensions are of the smallest, and its aspect of the rudest. A feeble yellow flame from a gas-light is all that illuminates it. All round us are troughs and bottles and water-pipes, and ill-conditioned utensils of various kinds. Everything is blackened with nitrate of silver; every form of spot, of streak, of splash, of spatter, of stain, is to be seen upon the floor, the walls, the shelves, the vessels. Leave all linen behind you, ye who enter here, or at least protect it at every exposed point. Cover your hands in gauntlets of India-rubber, if you would not utter Lady Macbeth's soliloque over them when they come to the light of day. Defend the nether garments with overalls, such as plain artisans are wont to wear. Button the ancient coat over the candid shirt-front, and hold up the retracted wristbands by elastic bands around the shirt-sleeve above the elbow. Conscience and nitrate of silver are telltales that never forget any tampering with them, and the broader the light the darker their record. Now to our work.
Here is a square of crown glass three-fourths as large as a page of the "Atlantic Monthly," if you happen to know that periodical. Let us brush it carefully, that its surface may be free from dust. Now we take hold of it by the upper left-hand corner and pour some of this thin syrup-like fluid upon it, inclining the plate gently from side to side, so that it may spread evenly over the surface, and let the superfluous fluid drain back from the right hand upper corner into the bottle. We keep the plate rocking from side to side, so as to prevent the fluid running in lines, as it has a tendency to do. The neglect of this precaution is evident in some otherwise excellent photographs; we notice it, for instance, in Frith's Abou Simbel, No. 1, the magnificent rock-temple façade. In less than a minute the syrupy fluid has dried, and appears like a film of transparent varnish on the glass plate. We now place it on a flat double hook of gutta percha and lower it gently into the nitrate-of-silver bath. As it must remain there three or four minutes, we will pass away the time in explaining what has been already done.
The syrupy fluid was iodized collodion. This is made by dissolving gun-cotton in ether with alcohol, and adding some iodide of ammonium. When a thin layer of this fluid is poured on the glass plate, the ether and alcohol evaporate very speedily, and leave a closely adherent film of organic matter derived from the cotton, and containing the iodide of ammonium. We have plunged this into the bath, which contains chiefly nitrate of silver, but also some iodide of silver,—knowing that a decomposition will take place, in consequence of which the iodide of ammonium will become changed to the iodide of silver, which will now fill the pores of the collodion film. The iodide of silver is eminently sensitive to light. The use of the collodion is to furnish a delicate, homogeneous, adhesive, colorless layer in which the iodide may be deposited. Its organic nature may favor the action of light upon the iodide of silver.
