Thanks Digitizer. You saved me from buying an enlarging head on Ebay to experiment. I do get beautiful scans from modern films. But if 40+ years old the colors are hard to adjust. Sometimes you get an image that is too green and too magenta!!!.
You also inspired me to post my rig on “Let’s see your DSLR film scanning setup”— My setup
Thanks again!! You saved me a lot of time and some money too.
