Automatic TTL and E-TTL Fill-in flash mode
The automatic TTL or E-TTL fill-in flash mode is activated by most cameras when
the automatic programme P is selected and by Vari or subject programmes
during daylight (see camera operating manual).
Fill-in flash mode overcomes troublesome shadows and produces a more balan-
ced exposure between subject and background with contre-jour shots.
The camera's computer-controlled metering system sets the most suitable combi-
nation of shutter speed, aperture and flash output.
Ensure that the contre-jour light source does not shine directly into the
lens, as this will interfere with the camera's TTL metering system!
There is no setting or display for automatic TTL fill-in flash in the flash unit.

distance at which the subject is correctly lit (see 5.2).
