Camera Metering Modes: Evaluative, Center Weighted, and Spot

What metering modes do

Metering is the step where the camera reads light in the scene and suggests an exposure. Before the camera chooses a shutter speed, aperture, or sensitivity, the metering system decides which parts of the frame matter. Your metering mode changes that decision.

The three patterns worth learning are evaluative (also called matrix or multi-segment), center-weighted, and spot. All of them feed the same exposure system, so after metering you can still correct the result with exposure compensation or by changing the settings yourself. For the full picture of how shutter speed, aperture, and ISO work together, see the exposure triangle.

Evaluative, matrix, and multi-segment metering

Evaluative metering is the modern all-around pattern. The camera divides the frame into many zones and compares the pattern of brightness with a library of common scene types. Some systems also consider the active focus point, faces, color, and distance information when that data is available.

Because it reads the whole frame, evaluative metering handles everyday scenes well: landscapes with bright sky at the top, street scenes with mixed tones, and casual portraits. It is the mode to keep on when you are moving between very different light and you want the camera to make the first guess.

No pattern is perfect. Evaluative metering can be fooled by a small bright window behind a subject or by a scene that is mostly white, such as snow. If the histogram shows clipping, nudge the result with exposure compensation instead of switching modes. If you are choosing a camera for lots of general photography, the best mirrorless cameras and best DSLR cameras guides compare bodies with strong auto exposure systems.

Center-weighted metering

Center-weighted metering measures the whole frame but gives extra weight to the middle. It ignores the exact focus point and instead assumes the most important part of the scene sits near the center of the viewfinder.

This is an easy mode to predict. A portrait with the face in the middle, a product shot on a table, or a flower in the center of the frame all benefit because the edges cannot drag the exposure away from the subject.

If you recompose after metering, lock the exposure first, then move the camera. For more on how the lens opening affects exposure and subject separation, see aperture explained.

Spot metering

Spot metering reads a very small area, usually the circle around the active focus point. It ignores the rest of the frame, which makes it the most precise and the most demanding pattern.

Reach for spot metering in high-contrast scenes: a backlit face, a performer in a spotlight, a bird against a bright sky, or a subject in deep shade. Meter the tone that matters, lock the exposure, and recompose before you take the shot.

This mode assumes the spot you meter should become a middle gray, so a white wedding dress or a black dog will push the suggested exposure off. Use the histogram to check the result. Spot metering is especially useful when the dynamic range of a scene is wide and one tone must be correct.

Partial, average, and highlight-weighted metering

Many cameras add a few other metering options. Partial metering is like a slightly wider spot and works when a full spot circle feels too small. Average metering reads the whole frame without favoring the center, a simple option for scenes with even tones.

Highlight-weighted metering gives priority to the brightest areas so bright skies and windows do not clip. It is a strong choice for outdoor video and for stills where preserving highlight detail matters more than matching an average.

• Camera makers use different names for the same concept, so check your camera manual for the exact menu label.
• Some bodies link spot metering to the active autofocus point; others always meter in the center. The setting is often called spot linked to AF point, and it changes how you aim the spot.
• In manual exposure, the meter still shows its recommendation, but you are free to ignore it and set the exposure you want.

Which metering mode should you choose?

A practical default is evaluative metering with an exposure compensation control nearby. Use it for daily mixed scenes and switch to center-weighted or spot only when the light is unusual or you need control over a specific tone.

To choose, ask yourself two questions: is the important subject near the center, and is one area much brighter or darker than the rest? If the answer to both is yes, spot or center-weighted metering will help. If the scene is mixed, evaluative is usually right.

In fully automatic modes the camera may make some choices for you, so use Program, Aperture Priority, or Shutter Priority if you want the metering mode to have a consistent effect. The mode dial guide walks through those settings. When comparing cameras, look for a responsive exposure compensation control and the metering patterns you actually plan to use; guides such as best APS-C cameras and best full-frame cameras summarize the controls of current bodies.

Metering, exposure compensation, and raw

Metering only proposes an exposure. In Aperture Priority the camera changes shutter speed, in Shutter Priority it changes aperture, and in manual mode it shows the difference between your settings and its recommendation. The metering mode tells the camera what to measure, not how to write the file.

If you shoot raw, the pattern can matter because it decides where highlights and shadows land in the captured image. It does not change the way the raw file is encoded. See raw format explained for what those files preserve.

After any metered exposure, check the histogram. When the image is too dark or bright, use exposure compensation rather than jumping between metering modes on every shot. A steady workflow is to trust one pattern for each kind of scene and make small corrections.

What to pick for your use

Questions

Are evaluative and matrix metering the same thing?

They are different names for the same basic idea. One maker calls it evaluative, another calls it matrix, and several others call it multi-segment or multi. Each maker applies its own algorithms and scene data, so results can differ between cameras, but the concept is the same: analyze the whole frame and suggest an exposure.

When should I use spot metering instead of evaluative?

Use spot metering when one small area is the most important part of the scene, such as a backlit face or a performer in a spotlight. Use evaluative when you want the camera to balance the whole frame and you are not sure which tone matters most. In even light, evaluative is the simpler choice.

Does metering mode affect raw files?

It affects the exposure settings the camera suggests, so it affects the raw data that is captured: a different metering mode can make highlights clip or shadows block up differently. Once the image is recorded, the metering mode does not change the file. The raw file still holds the sensor data at whatever exposure you captured.

Do I need a different metering mode for video?

Many video shooters prefer highlight-weighted metering to protect bright skies and windows, or they switch to manual exposure. The metering patterns on stills cameras carry over to video, but the exposure should not shift dramatically mid-shot, so manual control and tools like zebras and the histogram often matter more.

Can I use exposure compensation in every metering mode?

Yes. Exposure compensation shifts the suggested exposure no matter which metering mode you have selected. It is often the fastest way to correct a spot reading of a white or dark subject. In manual exposure mode, exposure compensation may be disabled because you control all three exposure settings directly.

What metering mode should a beginner start with?

Start with evaluative or matrix metering in a semi-auto mode such as Aperture Priority. It makes good guesses in mixed light, and you can learn to correct the result with exposure compensation. Once you understand how the camera reads a scene, try spot metering in high-contrast situations. See the camera mode dial guide if you are unsure which mode to use.
