Exposure Compensation

Exposure Compensation


  1. A camera setting that allows the photographer to adjust the exposure level of an image, either making it brighter or darker than the camera’s automatic settings would produce.
  2. Typically measured in stops or fractions of stops, with positive values increasing exposure and negative values decreasing it.
  3. Commonly represented by a scale or dial, often denoted with the symbols “+” and “-”.


Exposure Compensation is a feature found in most modern cameras, including mobile cameras, that gives photographers the ability to override the camera’s automatic exposure settings. This is particularly useful in situations where the camera’s auto-exposure function doesn’t accurately capture the scene, such as in high-contrast or backlit conditions.

How It Works


The unit of measurement for exposure compensation is the “stop.” A stop is a doubling or halving of the amount of light that reaches the sensor. For example, +1 stop doubles the amount of light, making the image brighter, while -1 stop halves it, making the image darker.


Most mobile cameras allow you to adjust exposure compensation through the touch interface. Usually, a slider or a dial is presented on the screen, allowing you to easily increase or decrease the exposure.

Use Cases

Overcoming Limitations

While mobile cameras have increasingly sophisticated algorithms for determining the best exposure, they can still struggle in certain conditions such as high-contrast scenes, low-light conditions, or instances of backlighting.

Creative Control

Apart from practical applications, exposure compensation can also be used creatively. For example, underexposing a sunset can create a dramatic, silhouette effect.

Advantages and Disadvantages


  1. Greater Control: Provides more control over how the final image will look, bypassing the limitations of auto-exposure.
  2. Flexibility: Allows photographers to adapt quickly to different lighting conditions without having to fiddle with more complex settings like ISO, aperture, and shutter speed.
  3. Ease of Use: Most mobile cameras make it fairly straightforward to adjust exposure compensation, often with just a few taps or swipes on the screen.


  1. Limited Range: Mobile cameras generally offer a more limited range of exposure compensation compared to DSLRs or mirrorless cameras.
  2. Overuse: Heavy reliance on exposure compensation can sometimes result in unnatural-looking photos if not used judiciously.
  3. Battery Drain: Using exposure compensation frequently may lead to quicker battery depletion, as the sensor and processing unit have to work harder.

Best Practices

Use Sparingly

Avoid extreme exposure compensation unless it serves a creative or functional purpose, as it can lead to loss of detail in the highlights and shadows.


Always review the photo immediately after taking it to ensure that the exposure compensation has had the desired effect.


Remember to reset the exposure compensation back to zero after you’re done, to avoid mistakenly applying it to future shots.


Exposure Compensation is a valuable tool for both novice and seasoned photographers using mobile devices, offering a quick and easy way to adjust exposure levels. Whether for overcoming the limitations of auto-exposure or for creative purposes, this feature enhances the control and flexibility one has over the final image. However, it’s important to use this tool judiciously and be aware of its limitations to get the best results.
