I was thinking of replacing my existing condensor light source with a Dichro 45S Color head, mostly so I could use the diffusion light source and the dial in contrast setting vs. filters, in my b&w printing. I use VC paper, and in tray Ilford filters currently. Is there anything I should be concerned about in going from the condensor setup to the dichro setup? Is there anything to especially check or wear out on the dichro head? Thanks in advance. Steve.
