I guess I must have figured I needed to end the year with one more bone-head move.
After cutting down a sheet of 8x10 green-sensitive x-ray film (repackaged Kodak, if the seller is to believed), I shot a few table-top set-ups in 4x5 to test exposure - regular room light, 8 sec. exposure. Shot at 100, it went in the Uni-Color drum with a couple of sheets of Foma 100 and some Rodinal 1/50. Everything seemed to work out fine. So... figuring the usable starting film speed as ASA 100, I set up the 8x10 to test a lens or two for coverage at infinity. This time I shot out the door of my studio at the new fallen snow. Same development process, two seriously cooked negatives! Gee! do you think the blue and green light outside might be a bit stronger than that old yellow bulb hanging over the table??? Gotta be at least 2 stops overexposed. Doesn't do much to tame the contrast that way either.
Of course, I may have made some other errors along the way as well, using a packard shutter on the 8x10, but the meter was the same and I used the "instant" setting.
Ah, well.. live and learn. Happy New Year
