The texture of the printed image is of such peculiar character that neither brush or liquid paint seem capable of imitating it. - Alfred Horsley Hinton

The different degree of light interference between blue and red also affords a power which we may be glad to avail ourselves, in some cases using the red where a very marked degree of lightening is desired, or blue where only a trifling difference is needed.

Size, the mere number of square inches, of a picture, counts for nothing. A small picture may be quite as satisfying as a large; for remember that, as compared with the size of the mountain itself, the difference between a picture of it, thirty inches long, and one of six inches, is less than trifling.

...to be able to say of a representation that it is "exactly like Nature " is by no means equivalent to saying that it is a fine picture.
