    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

    Andy:

    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.
