Popped a roll of TMY in the Yashica D, set my meter for 200(dont ask why) and spent the morning out shooting. I had a couple of low light shots indoors on it that I knew would be thin, but I figured still usable. Unload and straight into the can, got out the D-76, thinking 1+1 and enjoy some fat negatives. Looking up, spied the Rodinal on the shelf, put D-76 away, Rodinal it will be, 1+50. Everything set up and temps perfect, time to mix. Heres where I have a brain-fart, I mixed it 5ml/500ml, and proceded to develope for 8 minutes. Half way through the fix, my lightbulb pops on, and the verbal "aw-s__t!" escapes my mouth unimpeded(good thing the kids were out). I mixed 1+100. What a dumb-a$$. I had some really sweet shots on that roll. Finish washing, rinse, pull negs from the reel to hang, hmm...not too awfully bad looking negatives. I have a couple that I knew would be thin are now iffy, but I've done much worse. I cant wait to feed them to my enlarger tomorrow and see how they actually print. I can only imagine how they would have turned out had I mixed the correct amount of developer, or souped them for the full 20 minutes called for that dilution.
