A question about BW paper developer temp

[Mainecoonmaniac]

I'm starting to use my old Beseler PM2L color analyzer again. Used it for printing color years ago, but I don't print much color anymore. Anyway, I've using it for BW printing. Currently, I'm running some test and calibrating the Analyzer for Foma BW paper and Ilford MG paper developer. I know if the temperature is off, my settings on my analyzer settings will be no longer valid. So does warmer developer increase the speed of the paper or just how fast the paper develops in the tray? Are there any APUGers using enlarger meters out there. If there are, how are you calibrating chemistry with your meter?

Thanks in advance.

Warm dev just increases the speed of development with Bromide papers, past about 26-27° C can increase base fog. However with Chloro-bromide papers increase temperature helps increase warmth slightly provided you compensate for the temperature rise by cutting the dev time.

Thanks Ian. I wish I had better control of the temperature of my darkroom! This the coldest winter here in Northern California in a long while.

Best,
Don

hi don

in addition to what ian said,
if you are using a glycin based developer,
the glycin likes it, and works best at about 72ºF
