Metering: What is it? And how do you choose the right mode for your shot?
Inside your camera is a light meter that reads the brightness of a scene by dividing the frame into sections and evaluating the light levels in each. You can control which areas of the frame it takes the reading from by selecting the suitable mode. Most cameras have three options: Spot metering The meter reads only the section where your focus point is set. This is good for correctly exposing subjects in high-contrast scenes. Centre-weighted metering Here, preference is given to the central sections of your frame, ignoring the outer ones. It’s good for close-up portraits and crowds. Matrix/evaluative metering The meter takes a reading from all the frames and gives you the best average exposure. You can further increase the contrast of a silhouette in this mode (*see settings on page 31), by decreasing the overall exposure manually (use the exposure compensation function) until you’re satisfied.
