Hi everyone! (my 1st post) I develop relatively small amounts of B&W 35mm at home and then scan them. For now I don't make analog enlargements, all the processing is in the computer. I shoot ILFORD Delta 100 and HP5. I use ID-11 for everything, because I'm still learning. I may eventually switch to Kodak D-76 which is cheaper here. I live in Chicago, and especially in the summer, I discovered that developing at 20ºC is an issue. The interior air temperature is 23ºC or more and trying to maintain 20ºC developer is impractical. I'd much more prefer to develop at 24ºC - this is my cold tap water temperature anyways (around 23.5ºC). Delta 100 packaging only lists 20ºC times at 1+0 or 1+1 ID-11 solution. QUESTION for you guys: what are the ramifications of switching to developing Delta 100 at 24ºC (1+1 or 1+3)? 24ºC would be like 7.5 minutes in 1+1, does it make sense to switch to 1+3 and extend the time? On Delta 100, I'd like to keep the grain as small as possible, as well as maintain smooth contrast, because I prefer to adjust contrast in digital post-processing. Can you share your wisdom? Thank you!
