ESC: Select this mode for optimal brightness level by increasing the number of stored fields.

NORMAL: Select this mode to use the electronic shutter and manual iris to control exposure. As

lighting conditions change, the camera adjusts exposure based on input from the electronic shutter.

BLC: Select this mode for scenes that are strongly backlit. The camera corrects the image to bring out the detail of the subject, such as a person entering a building through a door.

BLC + ESC: Select this mode to make objects in the center of the scene brighter. ESC adjusts the shutter speed according to the incident light levels.

5.If the object in the foreground is dark (unrecognizable) and the background is predominant, set ECLIPSER to ON, and then set LEVEL to 4 or 5.
