Again, if your correspondent cannot see why I "volunteered to instruct artists" or painters of backgrounds, perhaps he will allow me to inform him that I did so simply because background painters have hitherto supplied photographers with backgrounds totally unfit for use in the photographic studio. In spite of Mr. Wall's assumption of superior knowledge on subjects relating to art, I may still be able to give him a hint how to produce a pictorial background that will be much more natural, proportionate, and suitable for the use of photographers than any hitherto painted. Let Mr. Wall, or any other background painter, go _out_ with the camera and take a _carte-de-visite_ portrait out-of-doors, placing the subject in any well-chosen and suitable natural scene, and photograph the "sitter" and the natural scene at the same time. Then bring the picture so obtained into his studio and enlarge it up to "life-size," which he can easily do by the old-fashioned system of "squaring," or, better still, by the aid of a magic lantern, and with the help of a sketch of the scene as well, to enable him to fill in correctly that part of the landscape concealed by the figure taken on the spot; so that, when reproduced by the photographer in _his_ studio, he will have a representation of a natural scene, with everything seen in the background in correct perspective, and in natural proportions in relation to the "sitter." This will also show how _few_ objects can naturally be introduced into a landscape background; and if the distant scenery be misty and undefined, so much the better. It is the sharpness, hardness, and superabundance of subjects introduced into pictorial backgrounds generally that I object to, and endeavoured to point out in my paper; and I consider it no small compliment to have had my views on that part of my subject so emphatically endorsed by so good an authority as Mr. Wallis, in his remarks on backgrounds at the last meeting of the South London Photographic Society. I make no pretensions to the title of "artist," although I studied perspective, drawing from the flat and round, light and shade, and other things in connection with a branch of art which I abandoned many years ago for the more lucrative profession of a photographer. Were I so disposed, I could quote Reynolds, Burnett, and Ruskin as glibly as your correspondent; but I prefer putting my own views on any subject before my readers in language of my own.
