bought some kodak tmax 400 film the other day, mostly because i've heard very good things about it. the only problem is that it doesnt use C-41 processing. There isnt a lab close by that i can take my negatives to, so i usually have to use wal mart or some place like that. will they do black and white chemical photo processing? i'm a noob at the technicalities of film, mostly so i'm just kind of lost...does wal mart process non c-41 film? do you have to specify that it is not a c-41 film?
