I haven't had a lot of success. I think that the key is overexposure.
I've been advised to shoot neg film (such as kodak vps) at -3, and
process it in E6 +3. It sounds like too much, but the last test roll I
did was not so extreme, and is very dark.
I'm interested in hearing others' advice or opinions too, as well as what
you are doing with the process... I live in a tiny closet in manhattan so
I rely on processes that the lab can do for me...
