A Beginner’s Guide to Metering Modes in Photography

When you take a photo, your camera needs to figure out how bright or dark the image should be. This process is called metering.

Cameras don’t “see” the world the way our eyes do. Instead, they measure the light in a scene and suggest settings for the best exposure. Different metering modes tell your camera where to look when deciding how to expose the photo.

Understanding these modes gives you more control and helps you avoid common problems like subjects turning out too dark or backgrounds being blown out.

The Main Metering Modes

Most cameras offer three common metering modes:

1. Evaluative / Matrix Metering

• What it does: The camera looks at the whole scene and balances the exposure based on an average of all the light and dark areas.
• When to use it: Everyday shooting, landscapes, travel, and general photography.
• Why it’s useful: It’s the default mode on most cameras and usually gives reliable results.

2. Center-Weighted Metering

• What it does: The camera measures the entire frame but gives extra importance to the light in the center area.
• When to use it: Portraits, subjects in the middle of the frame, or when the background is brighter/darker than your subject.
• Why it’s useful: It prioritizes your subject without completely ignoring the rest of the scene.

3. Spot Metering

• What it does: The camera only meters a very small spot (usually 1–5% of the frame) right where you focus.
• When to use it: High-contrast scenes, backlit subjects, concerts, or moon photography.
• Why it’s useful: You can expose exactly for your subject, even if the rest of the scene is much brighter or darker.

Quick Metering Mode Reference

• Evaluative / Matrix – Best for general use and balanced exposures.
• Center-Weighted – Best when your subject is in the middle and background brightness is distracting.
• Spot – Best for tricky light situations or when you want full control over a small subject.
