Spring is here and I have decided to improve my knowledge of developers+film combinations. I've started to make a list but would be happy to hear suggestions for good/interesting combinations. My goal is to have more of an idea what result to expect, and just to generally learn more about film development. I mostly shoot medium format, and some 35 mm, and do a lot of lith printing as well as some alternative processes. For the past few years I've been looking to get a moderately contrasty an nicely grainy look, but now I find myself curious to look into a softer tonality. The films I've thought about including are: Rollei Retro 100 (I bought a lot of it at a good price a while ago and I've developed it in Rodinal and got nice, contrasty result.) Tri-X 400 (I've mostly tried developing it in Rodinal, and got grainy-in-a-nice-way result.) Ilford FP-4 (This and the HP-5 was my favourite in th 80s. I didn't know much about developing then, but I liked the tonality, and when I look at those negs now I thought it would be interesting to try these films again) Ilford HP-5 (see above) (TMax-100 or 400 - Not sure if I should include these. I was given them and I've never been able to get a result I'm happy with (Rodinal, D-76 and HC-110)) Developers: Rodinal (I've been using it for a while, mostly just 1+50, sometimes semi-stand or stand dev) ID-11 or D-76 (I understand these are fairly similar?) Xtol? Anything else? My plan is to shoot the same scene with the same camera and exposure (adapted for ISO) and then develop strips of the different films in different ways.
