It's light gray, something close to white but not white...

I use 1% formalin hardened gelatin. I think I'm going to up the gelatin
amount in the next batch to 3%... 1% doesn't seem to be enough for the new
exposure time (8:00 instead of 6:30).

It's stain in one sense (you can see it in the whites too), but it can be
due slight overexposure too. Will try the next one with 1/3 stop less
exposure and see what happens. I may not need to change the gelatin amnt.
if it doesn't stain the whites and I still get enough highlight detail...
More later.

What I said wasn't meant to be a firm statement or something like that.
That wasn't related to calibrations / curves etc. issue -> it's something
to relieve myself from the boring calibration stuff.

I can understand what you mean here! Will continue the boring stuff anyway...

On the other hand, I have something interesting / exciting to try now:
Pumice powder into arcylic gesso for prints on aluminum and/or Yupo!
