Recently, one of my trainees asked me about the camera metering modes function. This topic is a bit confusing for beginners, so I found it quite interesting for this month’s blog post.

What is Metering Mode?
Camera technology plays a crucial role in various specialized fields, including surveillance and security. For instance, dispensary live security surveillance systems address the unique challenges of monitoring sensitive environments while ensuring compliance with regulations and safety standards. Beyond reliable monitoring, these systems also enhance operational efficiency with features like motion detection, real-time alerts, and high-resolution imagery designed for specific industry needs.
When it comes to photography, understanding metering modes is essential. Cameras measure light by assessing how much the objects are reflected off, but not all objects reflect the same percentage of light. These variations depend on the material, and cameras calculate exposure based on the light reflected as an average of 18 percent gray. This helps determine the brightness of a scene and set the appropriate exposure.
However, certain situations can confuse this automatic calculation, such as photographing bright snow or a clear sky. In these cases, the camera’s measurement might lead to dull or inaccurate results, failing to capture the true beauty of the scene.
Adjusting the camera’s metering modes allows photographers to achieve accurate exposures and maintain image quality in challenging scenarios. It’s important to note that these metering modes are not available in Basic Zones, such as portrait, sports, or close-up modes.
What types of Metering Modes are in camera?
These metering modes vary in different camera models. You will find four types of metering in Canon cameras which have been listed below:
1- Evaluate Mode
2- Partial
3- Point
4- Center-weighted average
In Nikon cameras these names are different:
1- Matrix (Evaluate mode)
2- Point
3- Center-weighted average
What is Evaluate or Matrix Mode?
This is the default mode in most DSLR cameras. The camera measures the light intensity at several points on the scene and then combines and calculates them to find the required exposure. This mode works in most situations and it’s a good reason that has been set as default in most cameras. It’s good for landscape photography or even street photography.
What is Point Metering Mode?
With this mode, the camera measures a very small portion of a scene which is about 1 to 5 percent, and ignores the rest light of the scene. So the exposure is calculated based on the single point.
You can use this mode when you are photographing a bright background with a small dark foreground such as a bird in the sky or a person standing with the sun behind (but the person gets a small portion of the viewfinder). If you don’t use this mode then the subject will be too dark or even silhouette but this mode helps you to have enough light on your subject and keeps the details.
What is Partial Metering Mode?
This mode considers a larger area compared to point metering. It calculates 10 to 15 percent of the center of viewfinder. This mode mostly can be found in Canon cameras.
What is Center-Weighted Mode?
It covers 60 to 80 percent of the viewfinder. Use this mode when your subject is close to the camera, which means that your subject takes more portion of the scene such as a close-up portrait with backlight.
