DARK AREA OPTIMIZATION (IDR)
DYNAMIC RANGE
The contrast range of an object comprises all levels of brightness
from the brightest to the darkest point in the image. All levels of
brightness can be captured by the sensor, provided the contrast
range of the object is lower than the dynamic range of the camera.
In case of significant differences of brightness in the object (e.g.
shootings of interior spaces with bright windows in the background,
shootings with subject elements in shadow or directly lit by the sun,
landscapes with dark areas and a very bright sky), the camera with
its limited dynamic range will not be able to map the entire contrast
range of the object. Information in 'edge areas' will be lost (under
and overexposure).

iDR FUNCTION
The
iDR (Intelligent Dynamic Range) function allows an optimization
of the darker areas. Object details become much clearer.
Without iDR With iDR
You can specify beforehand if and to what extent you want to opti-
mize darker areas (
High, Standard, Low, Off). In the Auto setting, the
camera will automatically select the right setting depending on the
contrast range of the object.
In addition to that setting, the effect also depends on the exposure
settings. The function will have the strongest effect in combination
with low ISO values and fast shutter speeds. The effect is less pro-
nounced with higher ISO values and/or slower shutter speeds.
Factory setting:
Auto
▸ Select iDR in the main menu
▸ Select the desired setting
(
Auto, High, Standard, Low, Off)
Note
• The optimization of darker areas will slightly reduce differentiation
in very bright areas.
