lex_jenkins Posted August 31, 2003 Share Posted August 31, 2003 What you really need is an adjustment factor to translate the usual 20°C/68°F working times into something usable for the higher temperature. I have to contend with this routinely here in hot Texas (of course, it seems everywhere in the world is hot this summer). Ilford has a PDF on their website with a conversion chart. I'll attach a GIF with a variation of their chart. Somewhere in the recent photo.net archives is a multiplication factor that works well too as a starting point.
