Richard Pickup wrote in favour of amateur photographers due to the thoughtfulness and time devoted to the craft of film photography. Unlike commercial photography, amateurs are permitted time, expense and freedom of expression in their photography. Film lends a hand, in that the results are not immediate, that the time spent waiting for processing and return of the film (even if it is a few hours if one develops film at home) cannot be spared by commercial photographers in general.
Worth the read.
