I just got back a roll of NPZ 800 ISO film yesterday that I accidentally
shot at 100 ISO (3 stops underexposed) from a professional lab.  The negs
actually look get!  Better that 800 ISO negs.

Piers,

I have done this, but not with this particular emulsion. The "rule of
thumb" is to extend development (at 38C) by 30 seconds for each stop,
so for 2 stops push, develop for 4m 15s at 38C.

I got a noticeable increase in grain, but otherwise usable.
