Metering

Metering is a method of measuring the intensity of light from the object image, so the emphasis will affect the exposure settings in the shooting. Metering Mode commonly encountered are as follows:

1. Evaluative metering
Metering mode will adjust the weight point of light measurements automatically in accordance with the atmosphere of shooting, so this mode is very commonly used as a mode "all round" or in any situation

2. Partial metering
Metering mode is best used to obtain accurate measurements of light when the object is surrounded by a strong light images, such as when to capture an image object with a strong light behind him. This method works by measuring light focuses on the 9% the center of the frame image capture. This mode is very sensitive to light, so when using this mode and activate the self timer, make sure the view finder eye-piece closed with the cover (which is usually located on the original camera strap) so the light does not enter from the view finder, because the light coming in can cause calculation errors and produces images that under exposure.

3. Center-weighted average metering
Metering mode is best used when the object will megambil images with strong light around the object. On camera with auto focus sensor (AF) 9 points, when using this mode, the AF point that works just seven points located in the middle. Workings of this metering mode is the first measure of lighting objects in the middle of her back then to balance by measuring the overall mood lighting.
