Hey guys, sorry to dig up the thread, but I want to make a last post so this thread can be somewhat more useful.
I developed a second roll of Tmax400 with the exact same formula and ingridents I used before for the caffenol mix. This time I developed for ~18m with agitation for 10s every minute. The negatives still came somewhat underdeveloped. Really not that much difference from the first one execept for the 5 extra minutes in the developer. I wanna point out that I'm somewhat new to film photography, specially b&w film. The only other film I have to compare with is a Tri-X 400 pushed to 1600. Compared to the Tri-X I have way less grain and contrast with the negatives. But I guess this is somewhat normal? After all, the Tri-X is pushed 2 stops of it box-speed.
In fact I think I suffered from something I've heard about, it's called uneven development. Some frames seems just about right while other are clearly underexposed. Does anyone now why? I'm thinking it might have something to do with getting the film in the reel for development.
Still, I finally had a friend scan me the negatives on his Epson V500. He only scanned in medium quality and did no clean up on the negatives. They clearly show I need to improve my handling with them. As expected the underveloped frames have all the tones compressed in a narrow range, in contrast with the pushed film which clearly has a "bimodal" tone curve.
On a last note: the results weren't exactly what I expected, but Caffenol works for sure. Guess I just need some fine-tuning. Still, I might end up going after some "professinal" developer since I'm about to get a bunch of different films that I won't really have much "space" to keep fine tuning the time & mix for Caffenol. After all, I've only started developing to save money (and it is fun). Don't wanna strand to far from my objective, taking photos.
I appreciate all the help given, in special Jnantz.
