Many years ago, I worked as a commercial photographer. I was just out of
Brooks and worked for Bill Herbert Photography in San Jose CA. Bill had an
Omega D2 and used Varigam VC paper. He had a filter attachment mounted
below the lens that had two filters mounted in it, and a switching
solenoid. I forget the colors, I remember one being very dark and purpl'ie
and the other a yellow-green. Anyway, the enlarger timer also controlled
the filters. You dialed-in the paper grade you wanted, the time, then
pushed the expose button and the light filter (the home position) got a
percentage of the exposure, then the other (dark purpl'ie) filter flipped
under the lens. There was a solenoid that switched the filters. After the
exposure, it flipped back to the light colored filter so you could see to
change negs, crop, focus, etc.

This system was made up of a split filter system. A percentage to the
yellow-green light and a percentage to the blue-red light. Percentage
switched by the paper grade chosen.

Is this Split Printing?
