Partial Metering; Spot Metering; Centerweighted Average Metering; Af Point-Linked Spot Metering - Canon EOS 1D Instructions Manual

During continuous shooting in the spot metering mode, AE lock is set automatically
without the < > indicator displayed in the viewfinder.
C.Fn-13-2 can limit the manually-selectable AF points to only 11 while keeping the
spot metering linked to the center AF point. (→p.66, 136)

Partial Metering

This mode is effective when the background is much
brighter than the subject (due to backlighting, etc.).
The metering is weighted at the center covering
13.5% of the viewfinder area.

Spot Metering

This is for metering a particular part of the subject or
scene. The metering is weighted at the center
covering 3.8% of the viewfinder area.

Centerweighted Average Metering

The metering is weighted at the center and then
averaged for the entire scene.

AF Point-Linked Spot Metering

To make AF point selection faster, the selectable AF
points can be limited to 11 (C.Fn-13-1) or 9 (C.Fn-13-
3). When C.Fn-13-1 or C.Fn-13-3 has been set, the
manually-selected AF point is linked to 3.8% spot
metering. (→p.66, 136)
