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. This func-
tion will only affect images in JPG format.
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 pronounced with higher ISO
values and/or slower shutter speeds.
Factory setting:

( Auto , High , Standard , Low , Off )
Notes
• The optimization of darker areas will slightly reduce differentiation
in very bright areas.
• This function will only affect images in JPG format.
