To offset this effect a correction value can be set on some
cameras to manually match the TTL flash exposure to the
photographic situation. The actual extent of correction
depends on the contrast prevailing between subject and
background. The correction value is set on the camera.
Please refer to the camera’s operating instructions for details
concerning the settings.
A dark subject in front of a bright background:
Positive correction value (approx. 1 to 2 EV). Light
subject in front of a dark background: Negative cor-
rection value (approx. -1 to -2 EV).
Exposure correction by changing the lens diaphragm is not
possible because the camera’s automatic exposure system
will automatically regard the changed diaphragm as the nor-
mal working aperture.
After the exposure do not forget to reset the TTL flash
exposure correction back to the normal value on the
camera!
