How to Use DSLR Meter Settings

In our first lesson on metering modes, we talked about how to tell the camera which parts of the photograph are the most important. Matrix metering (Canon calls it Evaluative metering and Sony calls it Multi-segment metering) takes the entire scene into account and averages the exposure across the entire image. This is great for landscapes, but lousy for portraits with tricky lighting (such as the back lit scene below). By using more precise meter modes like center-weighted metering and spot metering, we can fine tune our camera’s meter and take better digital pictures.

So now that we understand the difference, let’s take a detailed look at how to use these settings. The method used to set the metering mode will vary by camera manufacturer and model. Refer to your camera’s manual under the subject “Metering Mode”. Most Canon and Nikon digital SLRs have a button with a metering mode symbol on it that you can hold down and then use the scroll wheel to change modes. Sony provides access to metering modes through the function button. The current metering mode you are using is usually displayed on your camera’s LCD window as well. You may have seen these symbols before and not known what they meant:

Matrix/Evaluative/Multi-Segment Metering Mode:

Center-Weighted Metering Mode:

Spot Metering Mode:

How to use your metering mode…
Now that you have your metering mode set, let’s talk about how to use it properly to gain your desired exposure. For center-weighted and spot metering modes, follow these few steps:

1. Center the part of the subject you are most concerned about (say, a person’s face) in the center of your view finder.

2. Press and hold the AEL button that should be near your right thumb when you index finger is on the shutter button.

3. While you continue to hold in the AEL, compose your shot as normal, press the shutter release button halfway to auto focus and take your picture! Your exposure settings will stay locked in as long as you hold that AEL button.

Knowing these less “automatic” camera settings, and most importantly when to use them, will help you take better pictures more often! If you have questions on how to do this with your specific camera model, please leave a comment and we will be happy to help.
