To the Editors.
Gentlemen,—I must beg of you to allow me to reply to Mr. Wall once more, and for the last time, on this subject, especially as that gentleman expects an answer from me.
To put myself into a fair position with regard to Mr. Wall and your readers, I will reply to the latter part of his letter first, by stating that I endeavour to avoid all personality in this discussion, and should be sorry to descend to anything of the kind knowingly. When I spoke of “independency and consistency,” I had not in view anything relative to his private character, but simply that kind of independence which enables a man to trust to his own powers of utterance for the expression of his ideas, instead of that incessant quoting the language of others, to which your correspondent, Mr. Wall, is so prone. As to his inconsistency, I mean that tendency which he exhibits to advocate a principle at one time, and denounce it at another. I shall prove that presently. Towards Mr. Wall, personally, I have neither animosity nor pique, and would take him by the hand as freely and frankly as ever I did were I to meet him at this moment. With his actions as a private gentleman I have nothing to do. I look upon him now as a controvertist only. So far, I hope I have made myself clearly understood by Mr. Wall and all concerned.
I also should like to have had so important a question discussed without introducing so much of that frivolous smartness of style generally adopted by Mr. Wall. But, as he has introduced two would-be-funny similes, I beg to dispose of them before going into more serious matter. Taking the “butcher” first (see the fifth paragraph in Mr. Wall’s last letter), I should say that, if I were eating the meat, I should be able to judge of its quality, and know whether it was good or bad, in spite of all the butcher might say to the contrary; and surely, no man not an out-and-out vegetarian, or lacking one of the five senses—to say nothing of common sense—will admit that it is necessary to be a “butcher” to enable him to be a judge of good meat. On the same ground, I contend that it is not necessary for a man to be an artist to have a thorough knowledge of perspective; and I have known many artists who knew as little about perspective, practically, as their easel did. They had a vague and dreamy idea of some governing principles, but how to put those principles into practice they had not the slightest notion. I once met an artist who could not put a tesselated pavement into perspective, and yet he had some right to the title of artist, for he could draw and paint the human figure well. Perspective is based on geometrical principles, and can be as easily mastered by any man not an artist as the first book of Euclid, or the first four rules of arithmetic; and, for all that, it is astonishing how many artists know so little about the working rules of perspective.
Again: Mr. Wall is surely not prepared to advance the dictum that no one can know anything about art but a professional artist. If so, how does he reconcile that opinion with the fact of his great and oft-quoted authority, Ruskin, not being an artist, but simply, in his public character, a voluminous writer on art, not always right, as many artists and photographers very well know.
Mr. Wall objects to my use of the word “artist,” but he seems to have overlooked the fact that I used the quotation marks to show that I meant to apply it to the class of self-styled artists, or men who arrogate to themselves a title they do not merit—not such men as Landseer, Maclise, Faed, Philips, Millais, and others of, and not of, the “Forty.” Mr. Wall may be an artist. I do not say he is not. He also is, or was, a painter of backgrounds. So he can apply to himself whichever title he likes best; but whether he deserves either one or the other, depends on what he has done to merit the appellative.
Mr. Wall questions the accuracy of the principles I advocated in my paper. I contend that I am perfectly correct, and am the more astonished at Mr. Wall when I refer to vol. v., page 123, of the Photographic News. There I find, in an article bearing his own name, and entitled “The Technology of Art as Applied to Photography,” that he says:—
“If you make use of a painted cloth to represent an interior or out-door view, the horizontal line must be at somewhere about the height which your lens is most generally placed at, and the vanishing point nearly opposite the spot occupied by the camera. * * * * I have just said that the horizon of a landscape background and the vanishing point should be opposite the lens; I may, perhaps, for the sake of such operators as are not acquainted with perspective, explain why. The figure and the background are supposed to be taken at one and the same time, and the camera has the place of the spectator by whom they are taken. Now, suppose we have a real figure before a real landscape: if I look up at a figure I obtain one view of it, but if I look down on it, I get another and quite a different view, and the horizon of the natural landscape behind the figure is always exactly the height of my eye. To prove this, you may sit down before a window, and mark on the glass the height of the horizon; then rise, and, as you do so, you will find the horizon also rises, and is again exactly opposite your eye. A picture, then, in which the horizontal line of the background represents the spectator as looking up at the figure from a position near the base line, while the figure itself indicates that the same spectator is at that identical time standing with his eyes on a level with the figure’s breast or chin—such productions are evidently false to art, and untrue to nature. * * * * The general fault in the painted screens we see behind photographs arises from introducing too many objects.”
Now, as I advanced neither more nor less in my paper, why does Mr. Wall turn round and caution your readers not to receive such simple truths uttered by me? I was not aware that Mr. Wall had forestalled me in laying down such rules; for at that date I was in America, and did not see the News; but, on turning over the volume for 1861 the other day, since this discussion began, I there saw and read, with surprise, the above in his article on backgrounds. I am perfectly aware that I did not say all that I might have said on perspective in my paper; but the little I did say was true in principle, and answered my purpose.
When Mr. Wall (in the second paragraph of his last letter) speaks of the “principal visual ray going from the point of distance to the point of sight, and forming a right angle to the perspective plane,” it seems to me that he is not quite sure of the difference between the points of sight, distance, and observation, or of the relation and application of one to the other. However, his coming articles on perspective will settle that. It also appears to me that he has overlooked the fact that my diagrams were sections, showing the perspective inclination and declination of the lines of a parallelogram towards the point of sight. In my paper I said nothing about the point of distance; with that I had nothing to do, as it was not my purpose to go into all the dry details of perspective. But I emphatically deny that anything like a “bird’s eye view” of the figure could possibly be obtained by following any of the rules I laid down. In my paper I contended for the camera being placed on a level with the head of the sitter, and that would bring the line of the horizon in a pictorial background also as high as the head of the sitter. And if the horizon of the pictorial background were placed anywhere else, it would cause the apparent overlapping of two conditions of perspective in the resulting photograph. These were the errors I endeavoured to point out. I maintain that my views are perfectly correct, and can be proved by geometrical demonstration, and the highest artistic and scientific testimony.
