Suggested backlight sources for scanning film with DSLR

As promised in my post in “Let’s see your DSLR film scanning setup!”… Here is the first Collimated vs Diffuse backlight source comparison using my partner Gabrielle’s photo taken with Nikon FM on Ilford HP5 Plus at The Vatican Christmas Day 1993. I’ve tried adjusting the diffuse lit image to match the collimated. I can get it close, but for black and white I will stick with collimated backlight. [HP5 Coll v Diff 01 Full Neg]
