A person or business that develops and prints photographs from film.
The photofinisher delivered the developed photos to the customer.
Photofinisher → It is formed from "photo-" (from Greek "phōtos", meaning light) and "finisher" (from Old French "finir", meaning to finish). The word refers to someone who finishes or develops photographs using light.
Think of 'light' ('photo-') being used to 'finish' ('finisher') a photograph — that's why a photofinisher is someone who develops photos.
