Hi folks -
I just finished souping some Kentmere 400 in D76. Temperature was 66F, so I adjusted development time per a handy chart. They look good.
My question is: My tapwater measures about 54F. I seem to remember from chem classes ages ago that the speed of a reaction doubles with a 10C rise in temp, and halves with a 10C drop. Is there a need to adjust the wash time? It really isn't a reaction, but....any thoughts out there?
In the same train of thought, as I remember high tempertures may cause reticulation of the emulsion. While I've never seen any evidence of thermal damage cause by a temperature drop, might I be courting disaster by having a 12F drop?
Thanks!
