Exposure Compensation: When & How to Use It

Exposure compensation is a feature on many cameras that allows the user to adjust the camera’s suggested exposure settings. It is often used when the camera’s meter doesn’t accurately reflect the scene being photographed (such as snow), resulting in an image that is too light or too dark. By adjusting the exposure compensation, the user can tell the camera to adjust its suggested exposure settings to produce a better-exposed image.

The amount of exposure compensation is usually measured in stops, with each stop representing a doubling or halving of the amount of light. For example, increasing the exposure by one stop will double the amount of light captured by the camera, while decreasing the exposure by one stop will halve the amount of light captured.

When to use it: Exposure compensation is useful in situations where the camera’s light meter may not accurately capture the desired exposure. This can happen when the scene has a high contrast range (such as a bright sky and a dark foreground), when the scene is predominantly white or black, or when the subject is backlit.

How to use it: The process for adjusting exposure compensation varies depending on the camera, but it is usually accessed through a dedicated button or dial on the camera body. Some cameras also allow you to adjust exposure compensation through the menu or by using a touchscreen interface.

Tips for using it: When adjusting exposure compensation, it is important to pay attention to the histogram display on the camera’s LCD screen. The histogram is a graphical representation of the tonal range of the image, with the left side representing the dark tones and the right side representing the light tones. If the histogram is heavily weighted to one side or the other, it may indicate that the image is either over- or underexposed.

Keep in mind that exposure compensation works in conjunction with your camera’s metering modes (evaluative, center-weighted, or spot metering) and will have different effects depending on the mode you’re using. It’s essential to practice and experiment to get a feel for how exposure compensation works with your specific camera and in various lighting conditions.
