Does anyone use a Omega F with the color head. I'm trying to get a good base for VC paper. It seems I have to be in the magenta 130 yellow 25 cyan 0 range to get a normal contrast print. This is not true with the Omega D2 with Ilford filters. Do the internal filters fade? Or am I just needing to test for this specific enlarger? Would be nice not to have different ASA for the same film. Moderators remove thread if it becomes to controversial.
