Metering Modes The camera has three metering modes: Evaluative, partial, and centerweighted average metering. Evaluative metering This is the camera's standard metering mode suited for most subjects even under backlit conditions. After detecting the main subject's position, brightness, background, front and back lighting conditions, camera orientation (horizontal or vertical), etc., the camera sets the proper exposure. Partial metering This is set automatically during AE lock in the Creative Zone modes. This is particularly effective when the background is much brighter than the subject due to backlighting, etc. This method uses a center area of approximately 9% of the screen. • The area covered by partial metering is shown on the left. Centerweighted average metering This is set automatically in the mode. The metering is weighted at the center and then averaged for the entire scene. 0LCD Panel Illumination To illuminate the LCD panel, press the button.
