Hi.
I have been trying to get my head round this and although I think I understand can anyone confirm:
Does the FE2 flash TTL metering system take the exposure compensation setting into account? Since the warning light will flash if the ISO setting is over the flash 400 limit it seems obvious that the ISO setting must be used, but the FE2 user manual indicates on pages 34 and 36 that exposure compensation is only used in A mode (although the exposure compensation light stays on for all but the M250 shutter speed setting). Since fill flash depends on the camera being in M mode that suggests exposure compensation won't be used (why would the flash TTL metering system take it into account when the main exposure metering doesn't?).
I have Thom Hogan's 'The Nikon Flash Guide' which indicates that the fill flash process ("for older cameras / flashes that don't allow flash compensation but have TTL") is as follows:
With flash off, establish correct aperture and shutter speed in M mode, then adjust either exposure compensation (e.g. -1.67) or ISO setting (e.g. increase by 1 or 2 stops), then switch on flash and take picture. The ambient exposure will be ok because the aperture / shutter speed were set in M mode before any adjustments were made and the adjusted exposure compensation / ISO setting will 'fool' the flash TTL metering system into shutting the flash output early.
This is a generic process intended to cover an unspecified set of older cameras and I just wonder if only the ISO setting is used by the FE2.
I could set up some tests to see what happens but there would not be a lot of point if someone can confirm that exposure compensation is definitely not used by the FE2. It might also be the case that what I've written above betrays a fundamental lack of understanding - and I'd be keen to hear about that as well.
Thanks in anticipation.
David.
