I know there are charts somewhere in this world... I know there are differences somewhere in this world... I know there is supposed to be a better place on this forum for this... But I get better answers from guys who can express themselves better here. That said here is my question. A) I shoot film and paper of course... b) I develop both in daylight tanks (even large format) c) Large format gets developed with two or three ounces of chemical. d) I try to get everything to 68 degrees but now and then I want to just pick up the bottle and read the temperature and develop the film. So question is: Is there a generaic temperature/time formula to use... something like for every degree you decress /add 10% more time... Something like that. If one of you guys knows, it would sure save me a lot of trouble. I use an off brand of film so the charts by manufacturers dont help me. Just some starting point would be fine.. I can always tweek it later.
