Keith (M) Posted August 15, 2017 Share #1 Posted August 15, 2017 (edited) Advertisement (gone after registration) Have only had my R5 a short while and have been using Neopan 400, which I expose at ISO 320. My other 35mm film cameras (M7 & MP) both have DX-readers, and yes, when I loaded Acros 100 into the R5 this morning, I clean forgot to reset the ISO dial. I had taken 16 frames, mostly of sunlit landscapes before realising. I see that Massive Dev chart gives development of Acros 100 @ ISO 400 in Rodinal 1+25 for 7mins 45secs. (Due to my development sessions being up to four months apart because of being out of the country, I only use Rodinal). Question - do I carry on exposing the remaining twenty frames at ISO 320 and develop as above or reset the camera to ISO 100, develop as normal and potentially kiss goodbye to the sixteeen?

Peter_S Posted August 15, 2017 Share #2 Posted August 15, 2017 (edited) Why not take the film out, push-develop the 16 shots at a little less than 7:45, and start a fresh roll? I you do not want to do that, I would finish the roll at 320.Else, I guess, you may want to google stand-development, since you are using Rodinal .

Soden Posted August 15, 2017 Share #3 Posted August 15, 2017 (edited) Since when does the MP have a DX reader?... news to me if it does. Anyway, finish the roll at the same ISO and make the appropriate adjustments per Massive Dev. Your photos will be a bit grainier, but that's all.

Keith (M) Posted August 15, 2017 Author Share #4 Posted August 15, 2017 Since when does the MP have a DX reader?... news to me if it does. Brain fade (again) The MP's dial is a much more obvious reminder to set ISO after closing the back. Quote Link to post Share on other sites More sharing options...
Soden Posted August 15, 2017 Share #5 Posted August 15, 2017 Brain fade (again) The MP's dial is a much more obvious reminder to set ISO after closing the back. I almost wish the M7 didn't have one, as the push/pull is counter intuitive. But back to topic... I shoot tri-x at 1600 frequently, for (cough cough) effect. Give it a try, finish the roll and adjust in development... you might like it... or not. 2 Quote Link to post Share on other sites More sharing options...
250swb Posted August 16, 2017 Share #6 Posted August 16, 2017 It's less than two stops under exposure, hardly anything, you could do that intentionally in certain lighting situations, give it a bit more development time to compensate if it wasn't a contrasty situation. 1 Quote Link to post Share on other sites More sharing options...
Keith (M) Posted November 3, 2017 Author Share #7 Posted November 3, 2017 (edited) Advertisement (gone after registration) Well, I finished off the film at ISO 100 in late August in the little village of Navajas in Valenciana. Arrived back from Spain a week ago and developed it today, choosing to use stand-development of 1 hour & Rodinal 5:100. And the result s are... 1) Exposed at ISO 320 2) Exposed at ISO 100 So Rodinal & stand-development came to the rescue Edited November 3, 2017 by Keith (M) 1 Quote Link to post Share on other sites More sharing options...
gbealnz Posted November 3, 2017 Share #8 Posted November 3, 2017 Looks good, (as does the one in the I Like Film thread) Keith. You'd never know. Gary 1 Quote Link to post Share on other sites More sharing options...
a.noctilux Posted November 3, 2017 Share #9 Posted November 3, 2017 Acros + Rodinal seem nice combo. Sunny Spain looks good. When I return there, South Spain, I'll give Acros 100 a try, maybe in screw mount Leica . Quote Link to post Share on other sites More sharing options...
Keith (M) Posted November 4, 2017 Author Share #10 Posted November 4, 2017 Ref post #7, I should have written Rodinal 1:100. Quote Link to post Share on other sites More sharing options...
adan Posted November 6, 2017 Share #11 Posted November 6, 2017 Good choice. Rodinal 1:100 (and "stand development") will maximize that developer's "compensating effect" and scrounge out every last bit of exposed silver in the shadows, without cooking the highlights. Outside of some "bald spots" in the black shadows under the trees, the overall tonality seems fine 2 Quote Link to post Share on other sites More sharing options...
pico Posted November 6, 2017 Share #12 Posted November 6, 2017 To add to Adan's good advice, I have found no advantage for 1:100 Rodinal stand development longer than 40 minutes. At 40 minutes is is truly exhausted. Quote Link to post Share on other sites More sharing options...
