Many photographers think they are photographing nature when they are only caricaturing her.
"Though many painters and sculptors talk glibly of "going in for photography," you will find that very few of them can ever make a picture by photography; they lack the science, technical knowledge, and above all the practice. Most people think they can play tennis, shoot, write novels, and photograph as well as any other person - until they try."
"Do not call yourself an "artist-photographer" and make "artist-painters" and "artist-sculptors" laugh; call yourself a photographer and wait for artists to call you brother."
Pay no heed to the average photographer's remarks upon "flat" and "weak" negatives. Probably he is flat, weak, stale, and unprofitable; your negative may be first-rate, and probably is if he does not approve of it.
