I have found a few threads on this topic, but nothing authoritative. In my appartment the temperature ranges from 17C (63F) in the winter to 31F (88F) in the summer. Although I carefully calculate my developer temperature to average out to 20C (68F) for Delta 400 in Xtol 1:2 and 24C (75F) for Delta 3200 in Xtol 1:1 (by keeping a bottle of distilled water in the fridge and mixing it with non-refridgerated water in the summer), how much does the temperature of the other solutions matter.(posted 8737 days ago)I figured that with hardened modern emulsions, even a 31C (88F) wash water would be OK if I handled my negs carefully, and so far I haven't experienced any visible problems. Does anyone think that the temperature of the baths other than the developer makes a visible difference in quality? By the way, although this is not the place for it, the same question applies to printing. Thanks in advance for your always so helpful combined wisdoms. Raja
