Understanding Exposure: what you need to know about light to take pictures that shine

    Correcting your exposures


    If too much light reaches your sensor, you’ll end up with over-exposed (overly bright) images, and if too little light gets through you’ll end up with under-exposed (overly dark) images.

    Your DSLR will meter the amount of light for you, and suggest an appropriate brightness for your shots – but it won’t always get it right. There is a simple way of taking control, though.

    Take a picture, look at it, then use the Exposure Compensation control to make the next shot brighter or darker.

    When shooting in P, Av or Tv modes, you can use Exposure Compensation to deliberately dial in a degree of under- or over-exposure (measured in ‘stops’), so you can change the overall exposure until you are happy with the result. We’ve illustrated how it works in the sequence below.
