Beseler Dichro 45 color 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!

For black and white, you can use them for setting the contrast of VC paper.

There are tables of the settings, though they seem different for different companies.

Why do you think the display is not correct?

As BeBu says, why do you think it`s incorrect?

Anyway... think that it doesn`t matter at all, as soon as you can achieve different contrast grades with it.

Think that with a split printing technique, you only need two filters to expose the sensitised parts of the emulsion; yellow and magenta (something like 200Y and 200M, although it will depend on the enlarger).

Midway filter settings just give you intermediate contrast levels, but here you need to have a bit of control to achieve perfectly linear results.

So don`t worry so much. Just print your negatives and check results!
