exposure/WB
To reproduce accurate colours, regardless of the prevailing light sources and colour tem-
peratures (measured in Kelvin), a correct white balance is required.
For this purpose, the camera provides the following white balance modes:
•
Auto
ATW (Auto Tracking White Balance):
This white balance setting automatically determines and permanently readjusts the
white balance value output using the colour information from the entire scene in order
to continually compensate for colour temperature changes in varying light conditions.
For best results, at least one white object (as reference white) should be within the
scene that is to be captured.
The use of ATW is especially recommended for scenes with constantly varying lighting
situations/colour temperatures, such as indoor scenes with artificial light sources and
incident daylight.
•
One Push
One-Push AWB (Automatic White Balance):
The “One Push” white balance value is a fixed measured value which is solely readjust
-
ed on behalf of a user request (
Apply
button). The adjustment is based on the assump
-
tion that, in correct lighting conditions, a white or neutral grey object takes up more than
half of the entire image.
•
Manual
MWB (Manual White Balance):
This setting allows you to manually adjust the white balance value to the prevailing
colour temperature using the slider
color temperature (K)
(available colour temperature values: 2500 – 6500 K).
By clicking the
oK
button, the selected colour temperature value is applied.
By clicking the
Get parameters
button, the white balance value is automatically recal-
culated using the colour information from the entire scene, or rather reset to the prevail-
ing colour temperature in the scene.
