Metering Modes

The EOS D30 uses three methods for metering: evaluative, partial, and center-weighted averaging.

The Easy Shooting zone uses evaluative metering. In the Creative zone, any of the three modes can be selected.

: Evaluative Metering

This is an all-around metering mode suited even for backlit subjects. The viewfinder field is divided into 35 metering zones to which the three focusing points are linked for evaluative metering. The camera determines the main subject’s size, position, brightness, background, front and back lighting, etc., so that it can select the proper exposure for the subject at all times.

●When using manual focusing, evaluative metering is based on the center focusing point.

: Partial Metering

This is particularly effective when the background is much brighter than the subject due to backlighting, etc. This method uses a center area of approximately 9.5% of the screen.

●The area covered by partial metering is shown on the left.

: Center-weighted Averaging Metering

This method meters the average exposure of the entire viewfinder screen, and gives extra weight to the center.
