Shutter WDR
: For scenes with high contrast or changing light conditions, the camera combines two
frames taken with slow- and fast-exposure shutter speeds into a single frame with a wide dynamic
range. The camera uses an algorithm that determines the optimal mix of light and dark regions
within the scene.
Min Shutter Speed
(available when Auto Exposure Mode is set to
Auto
or
Auto Iris
): Select a suitable
shutter speed according to the environmental luminance.

Caution
Using a slow shutter speed causes moving objects to be blurred.
Attention
L'utilisation de vitesses d'obturation faibles peut rendre les objets en mouvement flous.
