Ilford's packaged ID-11 1+1 has been one of my standard developer for a few films including PX and HP5+. However, I have qualitatively observed that if I use this developer at 25C with time adjusted for comparable shadow speed, I get higher highlight contrast. This is in contrast to Microphen 1+1 with which I can almost always process at 25C with adjusted time for nearly identical result to my eyes.(posted 8489 days ago)If this is due to hydroquinone in ID-11, then D-76H presumably produces little change in contrast at 25C compared to 20C. Is this indeed the case? I've seen here John Hicks mentioned using D-76H at 24C and I think if D-76H allows me to process at 25C without boosted contrast then it is well worth mixing myself and forget about packaged ID-11... (since I rarely process 20 roll films at a time - even though I have more than 20 rolls sitting here to be developed...)
