10 camera techniques to master in 2014: how to use exposure compensation
In this section we’ll look at how you can get your exposures spot-on in different lighting conditions using exposure compensation.
Deciding whether to increase or decrease the exposure of your shot can be puzzling, as the adjustment you need to make is often the opposite of what you might at first expect.
Here’s how to use your camera’s Exposure Compensation function to lighten or darken your image.
If the subject contains mostly light tones you may find that your camera will under-expose your image. In this situation, you need to press and hold the Exposure Compensation button, increase the exposure by turning the dial right to enter a value of +1, then take the shot again.
If shooting a mainly dark subject, your camera is likely to over-expose the scene, so you may need to reduce the exposure. Press and hold the Exposure Compensation button as before, but this time turn the dial left to enter a value of -1.
Decipher the histogram
The easiest way to check the exposure of your shots is to use the histogram display on your camera’s rear screen when reviewing your images. This shows the distribution of tones in your shot, so you can check exposure as you shoot.
To get the most from this handy tool you need to recognise the characteristics of under- and over-exposed shots.
There is a gap to the left of the histogram, and the graph goes off the right-hand side.
