Very few people are nostalgic for the old days of photo processing: the interminable wait to see if you got even one decent image on a roll of 36 frames of film, the abject disappointment if you failed to, and the cost of prints and slides. If you had your own darkroom or worked in one, the routine included agitating film canisters by hand, mixing smelly chemicals, wielding tongs and washing trays, and the constant fear of light leaks. Wild horses couldn’t drag me back to those times, but I did have some interesting photo lab jobs over the years.
