Jerry,
That (loss of red light from the surface) wasn't an issue with flash
because you were, of necessity, working at a short range and the
flash was, for all practical purposes, the only source of light. I
also used #5 blue mostly and daylight film, mostly transparency
films. I also designed a custom flash gun that had a tilting head
calibrated to center on the object with Rolleinar 1 and 2 close-up lenses.
For distances beyond flash range, I used a CC 20R or CC 30R filter in
the Rolleimarin turret which could also hold one of the two close-up
lenses. They helped a little, not creating any more red light, just
cutting down the blue-greens.
Now with PhotoShop it should be a different story.
