6 TTL flash modes

6.1 Digital TTL flash modes

Depending on the camera system and the version of flash unit there are various digital TTL flash
control systems available:
Canon E-TTL II ; Nikon i-TTL ; Sony pre-flash TTL ; Olympus/Panasonic FourThirds- and Micro-
Four-Thirds TTL ; Fujifilm TTL.
In the digital TTL flash modes you can easily achieve very good results in flash photography.
The flash unit uses TTL measuring pre-flash technology:
When shooting, one or two TTL pre-flashes will be fired first by the flash unit.
The light of the TTL pre-flashes does not contribute to the exposure of the image.
The flashlight of the TTL pre-flashes reflected by the subject is taken care of by a sensor in the
camera. It measures reflected light through the lens (TTL).
In TTL modes, excellent flash exposure is straight-forward. In TTL mode, flash metering is taken
care of by a sensor in the camera. It measures reflected light through the lens (TTL).
The benefit of TTL flash modes is that all factors which could influence the exposure (filters,
changes to aperture and focal length for zoom objectives, extensions for close-ups etc.) are
automatically taken into account through flash light adjustment.

6.2 Automatic TTL fill-in flash mode

For most camera types, automatic TTL fill-in flash is activated in programmed auto mode "P"
and variable or subject programs in daylight conditions (see camera operating instructions).
With fill-in flash you can remove annoying shadows, and in back-lit shots a balanced exposure
can be achieved between subject and background. A computer-controlled measuring system on
the camera ensures appropriate combinations of shutter speed, working aperture and flash
output.
