A FULLY AUTOMATIC
Use this fl ash mode to achieve very good fl ash shots very simply.
The camera controls the fl ash exposure. It measures the light
refl ected from the subject through the lens (TTL).
Depending on the camera, the camera fi res an almost undetect-
able measuring prefl ash from the fl ash unit prior to the actual
exposure.
All of the camera's exposure modes, i.e. programmed automatic
( P ), shutter priority ( S / T ), aperture priority (
( M ) can be set.
TTL FULLY AUTOMATIC
As with A , however you can infl uence the fl ash illumination by
entering a fl ash exposure compensation of -2 to +2 aperture values
(EV) in half steps.
Reason:
Automatic fl ash exposure control is based on a refl ectance of 25 %
(average refl ectance of subjects). The subjects illuminated by the
fl ash light may therefore in some cases be over or under exposed:
– the main subject is very dark or very bright/highly refl ective
– an (averagely bright) main subject is very small and/or in front
of a very bright or heavily refl ective background (e.g. with backlit
shots), or in front of a very dark background (e.g. with night
shots)
• The status LED lights up as an indication that fl ash exposure
9d
compensation can be set.
