Why You Should Strive To Get The Proper White Balance In CameraGetting your white balance right in-camera not only saves you time in post-processing, it also gives your images a much more polished look. If your white balance is way off when shooting, chances are that, even after some clever post-processing, the white balance will still not look quite right, particularly when the white balance is way off in the camera.
Think of light being measured in kelvins in the same way that temperature is measured in degrees.
The cooler the temperature of the light, the higher the number of kelvins will be. As you can see below, shade, which we know is very cool because whites in a photo in the shade often look slightly blue, is around 8000K, whereas incandescent light is in the ballpark of 3000K. This is why shooting indoors at night often results in images with an orange or red cast:
How does this affect your image in camera? Well, each of your white balance settings affects the image based on whether you are shooting in cooler or warmer light.
For example, if you are shooting in the shade, which is a very cool temperature, setting your camera's white balance to shade (rather than cloudy or direct sun) tells your camera that it needs to compensate for this coolness by adding in more warmth to the image. This is how to achieve a true white in your image's brightest highlights.
On the other hand, if you are shooting in incandescent light, which is very warm, then your camera's white balance setting will cool down the image so that it is not too orange or red.
Another way to think about white balance settings is to take an image and apply various white balances to see the effect.
As you can see below, the Shade setting is too warm - this is because the photo was shot in the sun, so adding the warmth that the Shade setting provides makes the image too yellow. Direct sun is the proper white balance here because the subject is in the sun! Notice how using the correct white balance setting makes the white of her dress a pure white, with no hints of yellow or blue.
Experiment with the white balance settings on your camera to see how they affect an image. Once you understand how kelvins work, you can also use the Custom setting on your white balance menu to get the white balance perfect in camera. The Custom menu on your camera will allow you to manually set the white balance by entering a value in kelvins.
