Dichroic separate RGB channel DSLR scaning

[Harry]

I’m wondering if you might be referring to use a dichroic enlarger to try and produce separate RGB exposures, I’m not sure that would be possible, the only solutions that I’ve seen use individually controlled (and specially selected) LEDs as in this thread:

Integrating sphere as a uniform backlight

I am using a Nikor/Honeywell 6x7 colour enlarger head as a light source for my camera scanning setup. The enlarger heads light is an MR16 Halogen bulb, it shines into a wedge-shaped box which is metal, painted white, and has what looks to be styrofoam lining the inside, it then shines down through some translucent white plastic material which further diffuses the light. So it does what your globe does. My question is, how well then does the Halogen bulb work in terms of getting good colour info…
