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 photographic
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 photographic subject such as an outdoor sub-
ject with auto iris lens. Be aware that flicker may occur when a photographic 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 photographic subject has a bright light such as a spotlight in its background, the sub-
ject 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.
