Is my 50mm lens actually a 60mm lens???
Okay, so I shoot a M4-P on 35mm film with a 2:3 ratio frame.
I develop the film and print on 8x10 paper. Of course I need 8x12 paper in order to print the totality of the film. Since I can't do it, I crop. I want to keep the 8 inch intact so I end up cropping 2 inches up and down to make a 8x10 print.
Does this make my 50mm lens a 60mm lens? Do I gain DOF in the image?
What do you have to say on this?
