First, is there any disadvantages to developing a colour negative in black and white. For example do you lose contrast etc.(posted 8516 days ago)I too think you really mean printing colour negs on b&w paper (see Marc's answer), but if you really mean what you say I would ask why do you want to do this? It's not something you should start mucking around with at 1st. Having done this (just to see what would happen) recently and the results of Fuji Superia 400 in Ilford LC29 B&W developer were HIGH contrast negs with extremely dense orange mask, however it could be scanned and printed thru. I exposed it at 400asa and metered with the camera and exposure wise, they don't seem to bad!
