When to use Evaluative, Partial, Spot, or Center-Weighted metering. Updated:  Practical Guide to Canon EOS R Metering Modes The Four Canon EOS R Metering Modes Evaluative Metering : This is the default, general-purpose mode that assesses the entire frame, balancing highlights and shadows, and automatically adjusting for backlit subjects. Partial Metering : This mode measures light from a larger central area (roughly 5% to 6% of the frame). It helps when your subject is heavily backlit or stands out against a much brighter background.
