There is also an alternative for your lab claiming that they could print on b&w paper but they needed different chemicals. Kodak makes Ektamax and AGFA also makes a chromogenic paper made to go threw regular RA-4 chemistry. This paper does cost more per square foot so they would probably need to charge more. Also, the Kodak C-41 black and white films are very easy to print to a nuetral gray on color paper, if your lab printer says that it isn't then I would find a new lab.(posted 8656 days ago)
