346 THE PHOTOGRAPHIC NEWS. [July 17, 1863. 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 sun beam. Notwithstanding the fact that the process of making a pho tographic 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 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 Mac beth’s soliloquy 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. Con science and nitrate of silver are tell-tales that never forget any tampering with them, and the broader the light the darker their record. Now to our work. (To be continued.) Correspondente. PHOTOGRAPHIC REPRODUCTION OF PICTURES. Sib,—Do you not think that much of the bitterness of feeling between publishers of engravings on one hand, and certain unscrupulous photographers, on the other, might be avoided, and the growing taste of the general public for art fostered and encouraged by the plan I now propose for pub lishing the works of the celebrated artists of the present day. Suppose one or two, or more, of the leading photo graphers were to commission one of our best artists to paint an original work in monochrome, with the express under standing that it was to be copied by photography. When the work was finished the London firm could take negatives of the painting, and sell them to photographers in the country, who would agree to sell the prints, of a certain fixed size and at a fixed price. ' How much better and straightforward this would be than the miserable, sneaking way, of copying engravings, and running all the risk of the pains and penalties attached thereto. Again, how faithfully photography would convey the imprint of the artist’s mind, even to the very touch and manner of the painter. As one instance of the value of photography in repro ducing the work of the artist, look at the woodcut in the * Shown in the International Exhibition. Illustrated London News, of the painting of Caesar leaving the palace after the burning of Rome,* and look at the photograph of the same by the London Stereoscopic Com pany. The former gives no idea of the distance—the latter gives it in its most perfect form. So far as I have seen, all engravings seem deficient in this respect, from a woodcut in a newspaper to a fine line engraving; the effect of dis tance does not seem to me to be rendered near so truly as by a good painting or photograph. Of course, this case is an extreme one, and not a fair comparison ; still, it may serve, as being so familiar to many of your readers.—Yours, truly, Tnos. Gulliver. Union Street, Swansea. Photographi Zlotes an Quertes. Weak Printing Baths. Sir,—Under the above heading, one of your correspondents, who adopted'the nom de plume of “ Publicolo" published in your News, of the 24th of April last, a recipe as follows— silver 20 grains, nitrate of soda GO grains, to 1 ounce of water. From the day I received your journal of that date up to the present, I have used no other bath for my papers. I have never had a mealy picture, and but once have had occasion to clean my bath witii kaolin. I have used about a dozen 5 by 4' papers daily, and beg to enclose you a specimen. Amongst the many excellent suggestions published in your columns, none have been more valuable in a monetary sense than the above.—Yours obediently, An Amateur. [The print received is a brilliant, well toned print, quite free from mealiness.—Ed.] On Certain States oe the Atmosphere with Respect to Actinism. Sir,—In reply to Mr. Warner’s question as to the amount of actinism during the early part of this month, permit me to state that I was taking carte de visits portraits hero (about twenty miles north of Ross), on the 6th, 7th, and 8th of July, and my experience was quite the reverse of his. I never met with finer weather for the purpose, having obtained negative after negative in the open air, showing no trace of under expo sure in the details of foliage in the background, with exposures of from one and a half to two seconds. Amon, sulph. of iron de veloper, and in most cases only one application, no intensifying being required. The collodion, Horne and Thornthwaite’s new bromo-iodized, of which I can speak quite as highly as Mr. Warner does ; the lens, an excellent C. do V.,by Mr. Cox: the bath, an old one intended for the Fothergill process, and not intended for very rapid work. I may, perhaps, take this opportunity of mentioning a cir cumstance of the kind alluded to by Mr. Warner, which hap pened to myself last autumn. Some friends had appointed to come here on a certain afternoon to bo photographed for a rela tive in India. Being desirous of producing a good result I took all the usual precautions, carefully preparing fresh developing solutions, testing the bath, &c. About mid-day the weather began to get rather dull, yet I thought longer exposure would enable us to take good pictures. However, on trial I found that no exposure, however long (and at last I gave exposures with the full aperture of a portrait combination, which would have been considered long with a landscape lens and small stop), would produce anything beyond the faintest trace of a positive. We were obliged to give it up after several trials, and I took the precaution of setting aside the bath and remaining developer for trial next afternoon, at the same hour, when everything went well, and good negatives were obtained with the same collodion and chemicals which had failed so utterly the day before. On examining the atmosphere after our defeat, I fancied that I could detect amongst the trees a very thin, faint haze, of a peculiar greenish yellow hue, such as I have never seen before or since; but, imagination is apt to play one tricks on such occasions, and I shall be glad to learn whether any one else has noticed the appearance I mention. It would bo well if all photographers who experience this mysterious phenomenon, would publish an account of the occurrence in one of the journals ; several instances are already
