7.1 AUTO Flash Mode
With the AUTO flash mode, the flash unit can be
used easily for flash photography. It is not necessa-
ry to select particular settings on the flash unit.
The AUTO flash mode is a simplified flash mode for
digital cameras without settings choices and/or the
camera mode “P mode" and the fully automatic
mode.

7.2 TTL flash mode
These flash modes offer a very simple method of
obtaining very good flash shots. Here, the exposure
is measured by a sensor in the camera. It measures
the light reflected by the subject through the lens
(TTL = "Through The Lens").
If the shot was exposed correctly, the correct expo-
sure indication will illuminate for about 3 seconds
(see 4.2).
When taking a shot, an almost imperceptible mea-
surement pre-flash is triggered by the camera prior
to the actual exposure process.
