JUIY 20, 1883. | THE PHOTOGRAPHIC NEWS. 451 surface. In this state the plate is rubbed with clean flannel slightly damp, and the plate can give off as many impres sions as desired. It must be carefully ascertained that the engraved plate is quite dry before applying the oil. Photographic Society of France.—At the last meeting some enlargements on gelatino-bromide by M. Lamy excited interest, the paper being issued from the firm of Hutinet. We have already spoken of this paper, similar to Morgan’s. Morgan’s paper is, however, more suitable for intense images, and forms negatives or positives equally well. These enlargements shown by M. Hutinet were obtained directly by diffused daylight, and in a few seconds. A portrait of the opera singer, Losalle, life-size, attracted special attention. M. Carette presented a new arrangement of objectives by M. Steinheil, each lens being three centi metres thick. One of the attractions of the evening was the projection on the screen, by M. Chapuis, of the Transit of Venus, and views of the place of observation. Such enter tainments are always appreciated, and there was no lack of assistants. M. Davanne’s Lectures.—The administrators of VEcole Rationale des Ponts e'. Chaussees have brought out the lectures delivered there this year by our learned colleague, M. Davanne. It consitutes a veritable treatise on general photography, in which the principal methods of reproduc tion by the aid of light are reviewed with clearness and precision. Photo-Ceramic Lectures at Limoges.—Apropos of lectures, I may be permitted to state that my lectures are about to be given at Limoges, referring to all applications of photography to the decoration of porcelain, with which I am charged by the Minister of Fine Arts and Public Instruction. Limoges is a most important industrial centre for the manu facture and decoration of porcelain, and the audience will therefore be large and appreciative. Exhibition of the Graphic Arts in Vienna.—I have just seen a notice respecting the approaching exhibition of the graphic arts in Vienna. It states that heliographs will be admitted, to the exclusion of silver photographs. This ex clusion is quite right, and should exist in all exhibitions. Photographs, although graphic productions, are too unstable to be admitted into collections of publications, except they be carbon and platinum pictures. It is not, therefore, deemed necessary to make them the object of a special section. I should have liked to see an exception made in favour of direct photographs of assured permanence. LEON Vidal. THE TRANSLATION OF COLOUR INTO MONOCHROME BF PHOTOGRAPHIC MEANS. BY J. R. SAWYER.* The amount of interesting and instructive matter put down for your consideration this evening would seem to make it un- advisable that I should again occupy your time ; but the com munication that I wish to make to you springs so naturally out of the paper I read at your last meeting—is, in fact, so truly supplementary to it, and any value it may have would be so much impaired by the delay consequent upon the vacation—that I decided to ask to be permitted to again trespass upon your patience. On the last occasion I brought before you the results of photo graphing a screen of sixteen colours arranged in a curve, so as to give gradation of light and shade in each colour, and therefore giving the photographic value of each colour in every gradation from high-light to deep shadow; this screen of colours I again bring before your notice, and by its side I have placed an en largement of the best small negative I have been able to make of it. The negative from which this enlargement has been made is upon a gelatine plate, bromide of silver, with a trace of iodide, and I believe that, with our present knowledge, no better photo graphic translation of colour is possible ; but, however good this particular translation may be considered as the rendering of colour into monochrome, there is no disguising the fact that it is * Bead before the Photographic Society of Great Britain, painfully inadequate to render colour into monochrome so that its lights and shades shall impress the optic nerve of the eye in the same degree and in the same relation that the colours them selves do. A comparison between the colour-screen and the enlarged photograph will show what a great gulf still exists between what is possible at present, and what is necessary to be done, before photography can be considered able to translate colour into satisfactory monochrome. To take only a few instances, note the contrast between the energetic action of the yellow, No. 5, upon the optic nerve, with its extreme feebleness upon the sensitive plate. The blues, No. 3 and No. 10, both cool and retiring to the eye, are most energetic on the plate ; the browns, 13, 14, and 15, although so very different in value to the eye, come out pretty nearly alike in the photograph. The orange, No. 6, a darker colour to the eye than the bright yellow next to it, is rendered as being a much lighter and brighter colour ; in short, taking black and white as our standards, it is difficult to say which colour it is that photography does represent as being of the value that the visual organs attach to it . Fortunately, it happens that neither nature nor art presents colour in the sharp and decided manner that it is given on this screen ; nature blending and mixing her tints with wondrous skill, and the artist, being a faithful student, striving to put on canvas his transcript, exalted and emphasized by whatever of genius he may have in him. The result, then, of photographic transcripts from nature and art is not nearly so imperfect as might be imagined ; but there is still a wide difference between the value of colour as seen by the eye, audits value as presented in a photograph. But, then, it may be said, what is to be the standard for translating colour into monochrome ? Photographs are daily made that already render colour into very satisfactory mono chrome, and it may be asked what more can be desired ? What is wanted is the same translation that a skilful engraver would produce, and nothing less than this standard should be aimed at. Let me now call your attention to a coloured picture, a very common chromo-lithograph, which I was fortunate enough to secure, probably because it was so glaring in colour, and so wanting in any artistic merit, that it failed to find a purchaser even for the very small sum that I gave for it; in my eyes, and for my purpose, it had great merit, and I eagerly became the possessor of a work that would so admirably illustrate what I wish to lay before you. This we may imagine to be an Italian fruit-seller, a young girl attired in a white Garibaldi shirt, over which is a dai k blue bodice and dress ; she has an elaborate sash of green and red; her right hand supports a yellowish-brown earthen vase, whilst her left steadies a large basket of green and red grapes which she carries on her head ; the grapes are set off by vine leaves, and a strip of some bright red material hangs over one edge of the basket; her face, of an orange tint, is illumined by the setting sun, one-half of it being in shadow ; she wears a necklace of red beads, also one of bright yellow ; she has a back ground of greenish-blue lake, yellowish-green hill, and snow mountain, up which the blue shadow thrown by the departing sun is creeping ; the sky has a faint primrose tint near the horizon, fading gradually into blue sky towards the top of the picture. The special value, for my purpose, of this most inartistic work, consists in its violent and crude colouring. I felt that I had here a range of colour sufficient to test to its utmost all the photo graphic resources known to me. By its side I have placed an enlargement from the best dry plate negative I have been able to make ; and, before going further, I wish to call your careful attention to those points in which the photograph has failed in reproducing the value of the colour of the original. Take the red and green grapes in the photograph : they both come out of the same value ; but to the eye the red is, and should be, the prominent colour. The red patch of cloth hang ing over the edge of the basket comes up as a dark patch; the necklaces, although the yellow one is much brighter to the eye than the red one, come out of about the same value : the girdle of red and green, picked out with yellow, comes out more or less of the same tint, but the patches of yellow, being light, have got something like their value ; the earthen vase, being a yellowish- brown, is much too dark ; the red end of the girdle or scarf, instead of telling out as a bright colour, is of a similar value to the dark blue of the dress over which it hangs. I will not weary you by going minutely over the whole of the picture, but there are still two noticeable features that I must call your attention
