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.

9.2 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.
