WDR Pro (Wide Dynamic Range): Default is on. When set to Auto, you can select the strength of the
WDR function. The Low, Medium, High options correspond to the level of contrast between the overly-
lit area and the shaded areas. For example, the High option applies to a high contrast scenario. Note
that when the exposure time is set to longer than 1/60 second, the WDR function will be disabled.
■
Maximum gain control: Select a maximum value for the electronic gain from the slide bar. The gain
value also has its effect on the sensitivity of the IR cut lter. When applying the gain control, IR cut lter
setting will change accordingly.
IMPORTANT:
1. Because the exposure settings are also available in the Prole setting, incorrect congurations such
as a very high exposure level will let the camera consider it is operating in the Day mode even when
the ambient light is actually low. The camera will falsely remove the IR cut lter, and thus results in
distorted image colors.
Therefore, when the IR cut lter is in the Auto mode, the Prole setting is not available.
2. When set to the Night mode, the image display automatically changes to Black and White.
3. There is no Preview button in the Exposure window. Conguration changes are directly reected in the
live view window.
