I have been trying to tighten the reigns on my BTZS testing. In the past, I tested my film development and used a standard paper exposure scale (ES) of about 1.05 I think. Then I used VC paper exposed with a dichroic light source and everything came out fine.
Now I moved on from 4x5 to 8x10 and I am re-working things. My VC cold light produces lower contrast than the dichroic head I use for 4x5 so I think I need to adjust my film development to be a better match for the VC paper.
So my question is: is it better to err on the side of overdeveloped (higher contrast) negatives printed on lower contrast VC paper, or to err on underdeveloped (less contrast) negatives printed on higher contrast paper? If it makes much difference either way, what is the reason?
Based on my testing, I need to adjust development of the negatives from matching a paper ES of 1.05 to a new ES of ~1.2 on the cold light source. That would result in TMY2 processed in a Jobo 3005 in Xtol 1:1 at 68 degrees for ~8 minutes for an SBR of 7, FYI.
