Electro-selective pattern
Digital ESP-metering mode is used by some Olympus cameras. It measures the brightness of the center of the subject and the surrounding area separately.
Digital i ESP-metering is a focusing application: even when the subject is not in the center of the screen, focusing is possible; the AF target mark moves to the focus position. It gives better skin colours too.
Center-weighted metering mode meters the brightness over a wide emphasis on the center of the screen. This method is used when the surrounding area brightness may not affect the picture.
Spot-metering mode meters within the target area, the subject can be shot with optimal exposure regardless of the background light.
