What is your personal ISO speed for Fp4+?

So, what is your personal ISO speed for FP4+?

Andy, I usually rate it at 80 ASA, but it also fairs very well as low

as 50 ASA. I get good results using either Dixactol or FX39 as the

developer. Regards Pa

Chris Johnson's book on the zone system provides a series of tables

for different film/developer combinations. His tables show both 80 and

125 depending on the developer used:

Edwal FG-7: ISO 125

D-76 (1:1): ISO 125

Ilford ID11: ISO 80

HC 110: ISO 80

T-Max RS: ISO 80

Agfa Rodinal: ISO 125

Ilford Perceptol: ISO 80

FP4+ is not my regular film and I've never done any systematic testing

with it. I usually use it indoors with photofloods and an old 5x7

Kodak 2D. Under these conditions, I tend to rate FP4+ at or around ISO

50. Most films are rated lower for tungsten and, frankly, 50 is easier

to read on my Pentax spot meter! I normally develop in d-76.
