METERING MODE

Metering modes:

Matrix/Evaluative

The sensor takes readings from several points in the scene and compares it to different scenarios stored in memory. From this reading the camera tries to guess the meter reading. Here the camera measures the light intensity in several points in the scene, and then combines the results to find the settings for the best exposure. Matrix metering is ok for most situations.

Center Weighted
The camera takes readings from the center of the scene only. The center of the viewfinder has to be pointed at the area you want to meter. An advantage of this method is that it is less influenced by small areas that vary in brightness at the edges of the viewfinder.

Spot or semi-spot

Similar to center weighted only a much smaller area. You have to be accurate using this mode as it’s easy to aim off and get the incorrect reading. This mode is useful for metering really difficult scenes. Spot metering is not affected by other areas in the frame and commonly used to shoot very high contrast scenes. For more accurate manual metering use center weighted or spot. But as noted before you have to be careful with spot metering to get it just right
