We explain the basics of camera metering, metering modes and how you can utilize it for your photography. A camera’s menus may refer to this as Metering Modes, Camera Metering, Exposure Metering or just Metering. It is used to measure the brightness of the subject. It determines what the correct shutter speed and aperture should be. The camera optimizes exposures by adjusting shutter speed, aperture, and ISO sensitivity according to the brightness of the subject. It helps to control the exposure with minimum effort while achieving consistent and accurate exposures. Most DLSR cameras have several metering options. There are three main options and each option works by assigning a relative weighting to different light regions.
Matrix Metering (Nikon’s name) or Evaluative metering (Canon’s name) are default modes for most DSLR cameras. It divides the entire frame into multiple zones/areas which are then analyzed based on the light and dark areas. One of the key factors with matrix metering is where you set the camera focus point. After reading information from all the areas the metering system looks at where you focused within the frame and marks it the most important. If you are new to photography, this mode will work perfectly for you since it does a pretty good job of determining the correct exposure.
Center-weighted metering evaluates the light in the middle area of the image and its surroundings but disregards the corners since sometimes using the whole frame to determine the correct exposure is not ideal if you are, for example, taking a close-up portrait but in a bright surrounding. When using center-weighted metering mode the subject will be focused correctly but everything else will be overexposed.
Spot metering looks at the light around the focus point rather than the middle of the image. It gives you more control over the exposure than any of the other settings but it’s also the most difficult to use. Taking a picture of the moon would be a perfect example to use spot metering. Since the moon would take up a small portion of the frame and the sky is completely dark around it, the camera would only identify the light coming from the moon. Some DSLRs are also capable of multi-spot metering which averages out the light from the multiple spots.
