Looking at those beautiful photographic cartes-de-visite by Mr. Edge, I am very strongly impressed with the idea that they were suggested by some such artistic little pictures as Westall's Illustrations of the Poets. They are really charming little photographs, and show most admirably how much the interest and artistic merit of a photograph can be enhanced by the skilful and judicious introduction of a suitable background. I may as well observe, _en passant_, that I have examined these pictures very carefully, and have come to the conclusion that the effects are not produced by means of any of the ingeniously contrived appliances for poly-printing recently invented and suggested, but that the effects are produced simply by double printing, manipulated with consummate care and judgment, the figure or figures being produced on a plain or graduated middle tint background in one negative, and the landscape effect printed on from another negative after the first print has been taken out of the printing-frame; the figures protected by a mask nicely adjusted. My impressions on this subject are strengthened almost to conviction when I look at one of Mr. Edge's photographs, in particular a group of two ladies, the sitting figure sketching. In this picture, the lower part of the added landscape--trees--being darker than the normal tint of the ground, shows a _line_ round the black dress of the lady, as if the mask had overlapped it just a hair's breadth during the process of secondary printing. Be that as it may, they are lovely little pictures, and afford ample evidence of what may be done by skill and taste to vary the modes of treating photography more artistically, by introducing natural scenery sufficiently subdued to harmonise with the portrait or group; and, by similar means, backgrounds of clouds and interiors may be added to a plain photograph, which would enrich its pictorial effect, and enable the photographer to impart to his work a greater interest and beauty, and, at the same time, be made the means of giving apparent occupation to his sitter. This mode of treatment would enable him, in a great measure, to carry out the practice of nearly all the most celebrated portrait painters, viz., that of considering the form, light, shade, and character of the background _after_ the portrait was finished, by adapting the light, shade, and composition of his background to the pose and condition of life of his sitter. I shall now conclude my remarks with a quotation from Du Fresnoy's "Art of Painting," bearing directly on my subject and that of light and shade:--
