To overcome this problem in such a photographic
situation and still achieve a correct exposure in the
TTL flash mode,some cameras permit the flash
intensity to be influenced in TTL and E-TTL mode
(please refer to the operating instructions for the
given camera).
Flash units with an LC-display adapt the indicated
maximum flash range in TTL or auto mode A to the
selected flash exposure correction.
If a flash exposure correction is made in
conjunction with the EOS 1,1N, 1V,and 3, then +/–
marks appear additionally in the viewfinder.
Note:
Flash exposure correction is not possible in all
programmed image control modes (portraits,
landscape,close-ups, action,night program) and in
full auto mode (green square).
Some cameras permit flash exposure corrections
to be directly made on the camera. A flash
exposure correction set on the mecablitz has
priority over a flash exposure correction set on the
camera.
Any flash exposure correction can be combined
with a correction setting for ambient light (on the
camera).The flash exposure correction then
influences the illumination by flash, while the
correction setting on the camera controls the
exposure of the subject's background.
Flash exposure correction can also be adjusted on
the EOS 100,but this only influences the flash unit
incorporated in the camera.
