Night-shift equipment technician for the metro company, fixing escalators and ticket gates, off at daybreak. By day he repairs enlargers and timers for the shops on this street; one repair led to another, and he stayed to develop film.

Backstory

Night-shift equipment technician for the metro: escalators, ticket gates, off when it gets light. The darkroom is a daytime thing. It started with fixing enlargers and timers for the shops on this street; fix enough of them and eventually you stay to develop. A broken machine tells you where it hurts, he says. People don't. Which makes developing harder than escalators, and more interesting.
