First off: I hope discussion posts are OK? I don't see any rules except for tagging photo posts.
I have an old beseler B&W enlarger, no color filters or brightness configuration. I have a set of gels for contrast control.
When I'm printing 5x7 and I have my lens at the manufacturer's recommended aperture size, exposure times are very short (4-6 seconds). It's hard to get a good dodge/burn in such a short period. I can dial my lens down to f16, but even then I'm starting around 8 seconds for exposure, I'd like maybe 12-16.
I was thinking 1 or 2 stops of neutral density filter could slow down my exposure and give me more time to execute the print. Is that a thing people do?
