I know you can develop film in print developer for high-grain and contrast results. Is it possible to develop print in film developer, lets say D-76, and get different results?
Of course it is. The silver salts in paper are pretty much the same as in film - and the developers for both use the same chemicals. It will just take a lot longer to get an image.
I wouldn't bother if I were you.
Results for prints, excluding time effects, will be the same. Not worth the bother, though. Dektol 2:1 is still the standard for prints at minimal cost.
PS: Hertz van Rental is probably the greatest invented name since Ford Prefect.
