9.1 Automatic fill-in flash
Some cameras offer the facility of activating auto-
matic fill-in flash control or automatically trigger a
fill-in flash.
Fill-in flash will soften harsh shadows and diminish the
contrast, thereby producing a more balanced exposure
when shooting against the light. The camera's computer-
controlled measuring system automatically selects the
shutter speed, working aperture and light output in such
a manner that both the main subject in the foreground as
well as the background are uniformly exposed.
9. Flash techniques and flash functions
9.2 Exposure correction
Various cameras enable the user to influence the
TTL exposure control. Accordingly, the camera's
exposure settings can be corrected by up to ± 3
apertures (in one-third or half f-stop settings).
PLEASE NOTE: Do not forget to switch off this
function when it is no longer required!
Please refer to the camera's operating instructions
for further details.
9.3 Flash exposure sequences
Some cameras permit a sequence of shots to be taken of
the same subject with different exposure parameters.
When this function is activated, three pictures - as an
example - can be taken in succession: The first shot is
made with a negative flash exposure correction (less
light output), the second is normally exposed, and the
third is taken with a positive flash exposure correction
(more light output). For further details on this function
and the settings to be made please refer to the camera's
operating instructions.
