While the above answer is true, you can still develop XP2 like a normal B&W film, it's just that you lose the advantages of a chromogenic film. The exposure latitude is much reduced and of course there's no dye to cover up the grain, unless you use Pyro.(posted 8832 days ago)Anyway, home C41 kits are quite simple to use, they're 2 bath these days, exactly like B&W at a higher temperature, and with XP2 you can be a bit sloppier with the timing.
