I think interpolating between the FP and the standard mode is flawed. At full power, if the flash took 1/60th of a second, then flash sync at 1/250th, the shutter would be limiting the exposure, which it isn't. The slowest a portable flash unit ever fires is something like 1/1000. At fastest, about 1/10000. Studio units are usually fixed at about 1/1000, which is nice because it doesn't cause a failure of the reciprocity effect. 1/10000 can, but I've never noticed. But then again, I'm not very picky. > Yet another question in the same vein about the F100: How is it possible to > adjust flash intensity without adjusting background's one? I read that > bracketing could do so but is it possible to do so without using it? I don't see any way to do that. I have only the camera and the quick reference with me, not the full manual. Dan.
