I found my lost thread 'bout Delta 100.

I have now tested the combo at 12-15 minutes in Rodinal 1+50 (68 F, 10 sec. inversion every minute) and find 13:30 minutes doing the job for me when shooting portraits and 14-15 minutes when shooting anything else. What are your comments on my times. Massive Dev Chart says 14:00 minutes.
