Fixer is needed after development to make film or photographic paper insensitive to light. The category includes Ilford Rapid, Hypam and 2000 RT fixers, Foma Fomafix, fixers from Bellini, Ars-Imago and JOBO, as well as sodium thiosulfate and an odourless stop bath.

Rapid fixers shorten processing time, while universal fixers suit both film and paper. When choosing, check which material the fixer is intended for and the pack size – the range includes concentrates from 500 ml to 6 litres and Ilford Simplicity single-use sachets for small processing runs.
