Don, I have to disagree with you very strongly....1/10 of a degree? This is overkill, as a matter of fact T max is more sensitive to variations in agitation than it is to temperature. Back when I first got my densitometer I tested this. I plotted the different CI for T max developed from 70 to 78 F. The difference from one film to the next was very little, of course the difference between th 70 degree roll and the 78 degree roll was very great, but the rolls that only had one degree difference did not have a big change in contrast. What does make a big difference is agitation, this is a well known fact of T max films. If you wish to obtain the same results you need to agitate the same way. Although I agree with you that consistent darkroom practices will yield the best results, I am answering to your post because it this type of erroneous information that make beguinners paranoid and leads them to hate darkroom work! As a chemist I can tell you that 1/10 of a degree will not make a difference one way or another, give me a break! Althought there are many specialized chemical reactions that are dependent on rigorous temperature control, darkroom work is not the case.
