Metering Modes

Evaluative
This is the ideal metering mode for general shooting. If youre position the camera after focusing and include much darker or lighter areas in the frame, you should use the AEL(star)button to capture a newmeter reading before shooting.

Partial
The Partial metering mode bases the exposure purely on what’s in the central region of the frame. In evaluative mode, the bright pink petals would have lost their brightness and the centre of the flower and the bee would have been dark blobs.

Centre-weighted
Agreat metering mode for tricky lighting conditions, this focuses on what’s at the centre of the frame and takes much less account of light levelsat the periphery. Here it’skept thedark wall in silhouette and stopped the blue sky from washing out.

Spot
This bright white swan against a dark background is a nightmare for any camera’s metering system. To get a nicely balanced exposure, we’ve used Spot metering and taken a reading from the shadowy midtone area to the right of the swan’s lowerneck.
