Nitrile gloves when developing film in Pyro developers (whether tray processing sheet film or roll film in stainless tanks), tongs for prints in trays. I usually wear a plastic apron and old clothes. I now buy all my developers as pre-mixed concentrates, but when I mixed PMK from dry chemicals I wore a dusk mask and worked in an open garage. Long gone are the days when I stuck my hands into the film or print developer. I've known a few people who have suffered from photographic chemical allergies, and I want to be able to work in the darkroom for as long as I possibly can.
