Metering Modes Help How Your Camera Meter Works

Camera metering determines the correct shutter speed and aperture should be, depending on the amount of light that goes into the camera and the sensitivity of the sensor.

The most common metering modes in digital cameras today are-

1. Matrix Metering ( Nikon), also known as Evaluative Metering (Canon)
2. Center-weighted Metering
3. Spot Metering 

Some Canon EOS models also offer "Partial Metering", which is similar to Spot Metering.

camera metering modes explained

Matrix (Nikon)/ Evaluative(Canon) Metering:-

Matrix Metering or Evaluative Metering mode is the default metering mode on most DSLR. It works by dividing the entire frame into multiple "zones", which are then all analyzed on an individual basis for light and dark tones. One of the key factors that affect matrix metering is where the camera focus point is set to. The metering system looks at where we focused on the frame and marks it more important than all other zones.

We should use this mode for most of the Landscape photography.

Center-weighted Metering

Center-weighted Metering evaluates the light in the middle of the frame and its surroundings and ignores the corners. Compared to Matrix Metering, Center-weighted Metering does not look at the focus point we select and only evaluates the middle area of the image Use this mode when we want the" camera to the middle of the frame, which works great for close-up portraits and relatively large subjects that are in the middle of the frame.

Spot Metering

Spot Metering only evaluates the light around we focus point and ignores everything else. It
evaluates a single zone/cell and calculates exposure based on that single area.

This mode can use for Wildlife photography.
