I shoot mainly black and white in 4x5, 120, and 8x10, but I also shoot colour negative in those formats and want to take a whack at colour printing. I am especially interested in contact printing from 8x10 negatives. I am not interested in developing colour film at this time. When I do shoot colour, it is mostly Portra 160 NC. I have a DeVere 504 with Dichroic head and a Jobo CPE-2 with lift. I know nothing about colour printing so I am looking for recommendations of websites or books that that can walk me through it.
