A little thought, however, will show that both aerial and linear perspective play as important a part in the heavens as on the earth beneath. - Alfred Horsley Hinton

… generally speaking, a thin negative, one with a minimum of contrast and density, yet with just sufficient to give the amount of contrast required in the print, should be aimed at; but it must possess very soft gradation throughout.

...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.

The moment the eye perceives that the picture is produced by other than the professed means, the effect, the appeal to the imagination, is disturbed.
