Best way to deal with short printing time for RA4AThank you, I was thinking backwards. The amount of light in front of the lens is lower, but not behind.- kjm

Best way to deal with short printing time for RA4AAm I misunderstanding the Inverse Square law? The distance light travels lowers the intensity. A print made the same size with a lens that allows the enlarger lamp to be further from the paper would result in less light reaching the paper.

Best way to deal with short printing time for RA4AThank you for this. I can never really tell a difference personally but have tried to go with the recommended f/8 or f/11 just due to fear I might be doing something wrong. I am very new to both BW and RA4 printing, but especially RA4.

Best way to deal with short printing time for RA4AI have a similar problem, I get about 8 seconds at f/16 for a 6x6 negative on 8x10. I'm wondering if I should get a dimmer bulb, or put a dimmer in line with the enlarger.
