2. Method of controlling quantity of light [ALC/ELC]

The method of controlling the quantity of light is selected from the following in accordance with the lens to be used.

ALC (default): Adjusts the iris of the lens in accordance with the brightness of a subject. This selection is suitable for use of an auto iris lens (ALC lens).

ALC+: Controls the quantity of light with a combination of the electronic shutter and auto iris. This selection is suitable at shooting a bright subject such as an outdoor subject with auto iris lens. Be aware that flicker may occur when a subject is under fluorescent lighting.

ELC: Fixes the iris of the lens to a set value. This selection is suitable for use of a lens with fixed iris or manual iris.

Backlight compensation

•If a subject has a bright light such as a spotlight in its background, the subject appears shadowy because the camera adjusts the iris in accordance with the bright area.

•To eliminate this phenomenon, masking bright areas allows users to perform backlight compensation to hide bright areas.

•Backlight compensation has two modes: One is the PRESET ON mode for automatic com- pensation after sensing the light conditions on the camera side, the other is PRESET OFF mode for specifying the sensing area manually.
