At first when scanned I wasn´t quite as impressed as with effort no. 2. They seemed to be slightly flatter than the previous attempt. But after post-processing I think they turned out nicely. The micro contrast is still well controlled, and highlights are nowhere near being blown. Shadows are full of detail, if one would want to draw it out. Here are some examples (click for larger version, they do the pictures more credit):

I´ve been able to get consistent results, and results I like, over the last films. I will definitely continue using Caffenol for TMAX100 from now on. Next tests will be with TMAX400, I just need to get some first.
Try it out. Its not at all difficult. And the negatives do have a signature, if you like it, you need to try it out.
