Last night, my developing room temperature was at 77 degrees. I cooled all the water down to 75F for developing, so I figured all is dandy. After I had poured the developer out of my Jobo once it was through developing. I gathered a sudden urge to measure what the outcome temperature was. Turns out, it ended up at 76.4F !!!
Water temperature consistancy is great, just be sure to test actual temperature too! The humidity and heat bumped it up 1.4 degrees which can effect highlights by a whole stop!!!
Just a friendly reminder - Don't test just the water. Be sure to test the actual water in the tank!!!
