flash). Those compensations are cumulative! If you set
-1.7 EV on the external flash and -1 EV on the D300 body,
you’ll get -2.7 EV flash exposure compensation. Thus, you
need to be very careful about where you set flash
exposure compensation. If the D300 is your only Nikon
body then
always
set flash exposure compensation on the
camera body. If you also use a Nikon DSLR that doesn’t
have an internal flash and always use external flash, then
always
set flash exposure compensation only on the
external flash. The in-between cases are the ones that’ll
eventually catch you. Personally, I try to always use an
external flash and always set my flash exposure
compensation on the external flash. Whenever I have to
set flash exposure compensation on the body (e.g. I didn’t
bring an external flash and am using the internal one on
my D300), I always cancel whatever flash exposure
compensation I set on the body immediately after using it.
