After detecting the main subject's position, brightness, background, front and back lighting, etc., the camera sets the proper exposure. ¡ During manual focusing, evaluative metering is based on the center AF point. ¡ If the subject brightness and background light level are very different (there is a strong backlight or spotlight), use partial metering instead. w Partial Metering Effective when the background is much brighter than the subject due to backlighting, etc. Partial metering covers about 9% of the viewfinder area at the center. The area covered by partial metering is shown on the left. e Centerweighted Average Metering The metering is weighted at the center and then averaged for the entire scene. 71
