Ilford XP-2 is, in fact, a C-41 process film. Any pro lab should have no problem with processing it. Fact is, the cheap shops should also have no problem. The film goes straight in with all the other color film, no muss no fuss.(posted 9120 days ago)Unlike Kodak T400CN, XP-2 produces a true black & white negative. The lamps in the color printers need to be adjusted before the film is printed. Otherwise you will wind up with a sepia or blue cast to your prints.
T400CN has a dye in it to produce a black & white print on color paper with no adjustments needed.
