Dynamic Range and EDR
Dynamic range is the ratio between the brightest and darkest parts of an image or scene. A scene that
ranges from bright sunlight to deep shadows has a high dynamic range, while indoor scenes with less
contrast have a low dynamic range.
ranges from bright sunlight to deep shadows has a high dynamic range, while indoor scenes with less
contrast have a low dynamic range.
The extended dynamic range (EDR) feature will help capture the entire range of the scene. This feature can
achieve 12X the improvement in dynamic range. In scenes with very high dynamic range, the EDR feature
will exhibit a higher noise level than when the feature is turned off. This is normal and is not a
malfunction.

NOTE: Depending on the scene contrast, it may or may not be possible to capture the entire range with
any camera. Careful camera placement should be considered in extreme cases.
