I'm about to revive my darkroom, which has been sitting gathering dust

So I'm wondering if the place I have in mind for it is dark enough.

It's the bottom half of my live/work space which has no windows, at the
opposite end of the room which opens into the upstairs. I sat down there
for a while tonight to see how dark it was; after a few minutes, I could
just barely make out faint lightness at the other end of the room, but
could see nothing definite.

So I'm wondering if there's a rule of thumb about how dark is dark
enough. You know, something like the "sunny 16" rule about what can be
seen with the naked eye.

Yeah, yeah, I know I could make some test exposures with paper, but you
know what? I just don't want to. I'm not planning on making any
gallery-quality prints, just want to print the last couple of rolls of
film that I shot. So if you have any rough guidelines, I'm all ears.

My impression is that it's plenty dark enough, so long as I work fairly
efficiently and don't leave paper exposed to ambient light for too long.


I think it will be perfectly fine. In my (no so) darkroom I can see lots
of light under the door, and as far as the paper does not "see" it (I
don't know how express it, I just keep the sensible face of the paper
upwards: the light comes in from the floor) I never have had a problem.
Yes, I have made test exposures, no fogging.
