Sorry! That equation should have been (Dmax - Dmin)/Gamma. I was going to put Gamma to the minus one, but then realised I didn't know how to HTML superscripts.

Agfa now makes arial camera film (X 100) without the mask (orange color). This may become available in other formats but is currently available in 9" by 125' rolls (could be cut to 8 X 10). This film also has a surface that helps with Newtons rings on flat beds.
