Depends on the film, but for Tri-X and HP5+, I'm using Caffenol C-H(RS) for 15min@20C, agitate (gentle inversions) for the first full minute, then 10 seconds each subsequent minute. I've used C-M(RS) and C-L as well for different films. You'll probably want KBr if you're going to use C-H(RS) or C-L; I've done it with NaCl instead, but I wasn't thrilled with the results (you need a lot of salt to avoid bromide drags in my experience).
Looking at the blog, I will probably start with the classic C-M and Tmax 100 and see how that works out; I can add in the KBr after I get the hang of it. Thanks!
I find this a useful reference, at least for starting points: http://darkroom-solutions.com/#cdtc
I've done TMX for 12.5min@20C with good results.
I still have my Minolta X700 w/standard 55mm lens and a 70-210mm zoom/macro lens. Got the zoom to shoot out of a helicopter. I got my dad's equipment when he passed away. A Minolta X370 and a small assortment of lenses to include a doubler. Haven't used them in a long time since digital is cheap now. Don't have a fancy digital camera. Just don't take that kind of pictures anymore. My daughter has a nice one though.
For film, I have quite a few Praktica SLR bodies, but in Germany I only have my Praktica L with two Carl Zeiss lenses; one Tessar 2,8/50 one Pancolar 1,8/50. Unfortunately, the aperture is frozen wide open on the Pancolar, but it does appear to be serviceable, I just haven't the confidence to tear into it. I really need to get an M42 to EF adapted so I can try these lenses out on my T2i.
I also have a bit of old Argus kit, a TLR Seventy-five that I successfully was able to run a roll of 120 through, and an old Argus A2F from '39 that I fixed and was able to shoot with.
