Does anyone have information about the kind of contrast profile one gets for various b&w papers using a step wedge and color filters. I have just finished such an exercise on Arista II and Dektol 1:2. I was surprised to find that the greatest change occurred at the higher and lower ends of the filter range with very little change happening in the middle ranges. In fact my overall contrast ranged from 14 steps to 8 steps (pure white to pure black) but from filter #1-#3
(5 Kodak filters) I only get a one step increase. Is this normal?
Thanks
John
