Feature on some camcorders that allows users to adjust the exposure of an image by defining a spot on the LCD, either by touch or through the menu.
meters the light at the center of the imagae storage media: the medium that holds the recorded images
Determine optimal exposures for the Central area by measuring the light of that 3% area ONLY (10vs0). Useful for spot-lighted subjects or when you want to have optimal exposure for a specific point.
The camera's autoexposure system is focused on a very small area in the center of the viewfinder to critically adjust the overallexposure value ONLY for that area. see also: "Center-weighted" and "Matrix metering"
An auto exposure mode that sets the exposure based on a small circle in the center of the viewfinder.
In this type of metering, a central spot of the frame is utilized to measure the light that is coming off the subject. The measuring spot is often indicated by the viewfinder of the camera. Used without care, this system can easily result in the metered area being well exposed while the rest of the frame is either under or over exposed.
A metering mode found in many SLR cameras that judges exposure according to a small area in the center of the frame. Spot metering is useful for subjects with high-contrast, allowing you to meter both light and dark areas and then choose an intermediate exposure. Another use is for stage photography or other situations where subjects are lit selectively.
Autoexposure is based on a meter reading of a small circle in the center of the viewfinder.
