Balancing a burgeoning hobby alongside long work hours can be demanding. Bill Knight explains how stepping back from law helped him to develop his passion in photography

If you bought your first camera in 1956 it is likely to have been a Kodak. Mine was a Kodak Brownie Cresta, a chunky plastic box which took square pictures in, of course, black and white. It had two controls – the shutter button and a knob for winding on the film. If you did not wind the film immediately after each shot, you were in trouble: when you next used the camera you couldn’t remember whether you had wound on or not, so you risked the meaningless jumble of a double exposure if you didn’t wind on, or a blank if you did.
