What is different among the metering modes of DiMAGE 7? When do I switch them?
Multi-segment metering uses 300 segments to measure luminance and color to obtain the optimum exposure for general situations.
Center-weighted metering is a traditional metering method in which the system measures light values over the entire image area with emphasis on the center of the scene. This method is suitable when you want to optimize the exposure for the center subject.
Spot metering uses a small spot at the center of the image to calculate optimum exposure captured therein. This method allows exposure calculation for a perticular subject without being influenced by extremely bright or dark areas in the scene.
