I usually shoot with FP4+ and develop in D76 1:1 but I wanted to give Acros a try due to it's superior reciprocity characteristics when compared with FP4+. Since I was trying a new film I thought I may as well try a new (to me) developer, hence the Rodianl. The landscape scene was front lit about 3 hours after sunrise, Mamiya 7 with the 80mm lens and I rated the film at 100. The exposure was f8 at 1/500 (sunny f16 confirmed with my LunaPro SBC), range of tones from deep shadow up to cloudless sky. I developed the negatives last night, 13 min in 500ml Rodinal 1:100, 3 inversions after the developer was poured into the Paterson System 4 tank with plastic reel, one slow inversion every three minutes after that. Stop with the addition of 500 mls RO water for 2 minutes, 5 minutes in Kodak Rapid Fix (no hardener), water 2 minutes, permawash 2 minutes and then Gravity Works film washer 10 minutes. A couple drops of Photoflo in 500 mls water to prevent salt spots on the film... In an inverted scan of the negative there is shadow detail and it's a bit contrasty but the light was contrasty, there is still density in the sky which I did not expect since unfiltered blue skies always blow out on me. This morning I realized that I should have been using a 1:50 dilution of Rodinal. I've been reading so much on semi-stand development and I was in a rush last night so I guess that's my excuse. Still I'm quite pleased with the results. I'm guessing that the shortened time in developer is what allowed the highlights not to blow out, ie develop for the highlights. Question is should I do a 1:50 dilution and develop for 13 minutes next time or do the 1:100 with a 30' coffee cup swirl in the middle for a semi-stand development?
