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.
The EDR (extended dynamic range) feature will help capture the entire range of the scene. This feature can
achieve a 12 times 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.
