Beseler Dichro 45 Diffuser head

[tom_mccabe]

Good morning! I have an older Beseler Dichro 45 computerized color head. It seems to be working fine but the digital readout for each color does not work quite as well as I think it should. I've never used one of these before. When I turn the dials the color of the light changes but since the accurate readout is probably not correct, I think I can't be certain of the actual color of the light. I do not do color printing, only black and white. Does anyone have any ideas on testing the actual color of the light? I have them all visually zeroed out, as now the light is white. Forgive me if this is a dumb question, but I've never used a diffuser head like this before.

Thanks!!!

Unless you want to use the color filters to control the contrast of variable contrast paper, just leave them at 0. See Ilford's data sheets for their variable-contrast papers if you want to adjust contrast.
