Neopan 400 works well with D316. Here are curves comparing it with Tri-X. Notice that Neopan 400 compresses highlights less than Tri-X.

Here are the films I've tested with D316 so far, along with their dev-times, which all happen to be a whole number of minutes:

Tmax-400 ........ 12
Tri-X ............... 13
Neopan 400 ...... 14
FP4+ ............... 16

I plan to test Tmax-100, Acros and most Ilford films, including Pan F+. Any other ideas?
