The advance of photography is something like the progress of an army. The main body keeps in safe marching order, while the more daring and adventurous are the pioneers who lead the army—rushing here, feeling their way there; always skirmishing, often retiring, but eventually succeeding in finding new tracks and safe paths for the main body to securely pass along.

The professional, however, has all his energies directed to make things pay. He has too much at stake to speculate. He chooses the safest way. He is the true conservative, and when he gets hold of anything that works passable well, changes with reluctance. If an amateur experiments with a new toning bath on a batch of perhaps half-a-dozen prints, and fails, well the loss is not great, and he gains in knowledge and experience. But the professional has his batch of perhaps six hundred, and if he fail, the loss is something considerable...
(1863)
... it is not to be wondered that the impulses forward should emanate rather from the amateur than the professional. The former pursues the art for pleasure, the latter for profit. The one can try all manner of experiments, and whether he succeed or fail he secures his object—agreeable occupation.
