WDR Mode
The Wide Dynamic Range (WDR) mode allows for an improved colour reproduction and
detail resolution in scenes with extremely high contrast and strong backlighting.
In WDR mode, wide dynamic range images are produced by combining long-exposure
signals of dark image areas (normal shutter speed) with short-exposure signals of very
bright image areas (high-speed shutter) which then results in an improved dynamic range
and, thus, higher detail reproduction in both shadows and highlights.
Available WDR options:
•
Automatic
This option automatically enables or disables the WDR mode according to the prevail-
ing intensity difference of brightness levels between dark image areas and bright image
areas.
•
On
The WDR mode is always enabled.
•
Off
The WDR mode is always disabled.
Note that
•
changes in brightness and contrast may be observed in the image when the WDR
mode is enabled.
•
in WDR mode, the so-called “solarization effect” (complete or partial reversal of tones
with extreme bright light sources) may be observed with some objects. This phenom
-
enon only occurs in WDR mode and is not an indication of camera malfunction.

When selecting the AE Preset “Fluorescent”, the Wide Dynamic Range (WDR) mode is
automatically disabled.
A manual reactivation of the WDR mode in conjunction with the AE Preset “Fluorescent”
is not recommended.
