How do I change the metering mode? （EOS 50D）
Solution
The metering mode is the method of measuring the brightness of the subject. Normally, evaluative metering is recommended.
| 種類 | 解説 | ||
 | Evaluative metering |  | This is an all-around metering mode suited for portraits and even backlit subjects. The camera sets the exposure automatically to suit the scene. |
 | 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. |
 | Spot metering |  | This is for metering a specific part of the subject or scene. The metering is weighted at the center covering about 3.8% of the viewfinder area. |
 | Center-weighted average metering |  | The metering is weighted at the center and then averaged for the entire scene. |
To change the metering mode, follow the steps below.
1. Set the power switch to <ON>.
2. When the camera is ready to shoot, press the <
