Stop Bath — Film Dev Timer

A timer for people who develop their own black-and-white film. Pick your film, developer and temperature, and Stop Bath lays out the whole process — pre-soak, develop, stop, fix and wash — timing each step and prompting you when to agitate. The timer covers black-and-white processes only. The negative viewer works with both black-and-white and colour negatives. TIMES FROM THE DATASHEETS Development time depends on the film, developer, dilution and temperature. Every time in Stop Bath comes from a manufacturer datasheet, and the source shown on screen opens the original document so you can check it yourself. Where no official time exists, Stop Bath does not invent one. It says so plainly and offers an external reference for further research.
