| This is the camera's standard metering mode. 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 pont. If the subject brightness and background light level are very different partial metering should be used. |
Effective when the background is much brighter than the subject due to backlighting. |
The metering is weighted at the center and then averaged for the entire scene. |
This is for metering a specific part of the subject or scene. The metering is weighted at the center covering about 3.5% of the viewfinder area. |
