Editing Metering mode (section)

===Spot metering===
With spot metering, the camera will measure only a very small area of the scene (1&ndash;5% of the [[viewfinder]] area). By default this is the centre of the scene. The user can select a different off-centre spot or recompose by moving the camera after metering.  
Certain models support a mode which allows averaging of multiple spot meter readings, and some support metering of highlight and shadow areas.

Spot metering is not influenced by other areas in the frame. It is commonly used to shoot very high contrast scenes. For example, in a backlit situation a rising sun may be behind a person whose face will be much darker than the bright halo around the body and hairline. Spot metering allows the camera to measure the light reflected from the person's face and expose properly for that, instead of adjusting exposure for the much brighter light around the hairline. With the face properly exposed, the area around the back and hairline will become over-exposed. In many cases spot metering will over or underexpose a portion of the scene, so that the point of interest will be correctly exposed. 

Another example of the use of spot metering is photographing the moon. Other metering methods will increase overall exposure in an attempt to lighten the dark sky area, resulting in overexposure of the moon. Spot metering gives correct exposure of the moon and underexposes the rest of the scene which was dark already, so the low exposure is not noticeable. Spot metering may also be used for theatre photography, where brightly lit actors appear in a darkened auditorium. Spot metering is a method upon which the [[Zone System]] depends.
