In the past, I have always sworn by Xtol (1+2) as my film developer. I have noticed that for this developer, I always need at least 100ml of Xtol stock per roll of film to prevent underdevelopment.(posted 8925 days ago)Recently, I am shooting some extremely dark stage shots and will be trying Delta 3200 at 12,500 and developing it in Ilfotec DD-X. I ran a test roll today and developed it at the Ilford recommendation of 1+4 dilution (60ml + 240ml). The result was about 1 stop underdevelopment. Can anyone tell me whether this is caused by using less than 100ml of stock Ilfotec DD-X? If not, can anyone explain the underdevelopment I observed?
I have not varied my metering or shooting method. Should I compensate my metering in any way when shooting at 12,500? I am currently using EOS-3 as my primary body and Elan II as back up.
Thanks very much.
