What is White Balance?
Every light is a different colour temperature. For example, daylight is much cooler than a bedside lamp, which has an orange cast. You can adjust the White Balance in-camera, but if you shoot in RAW then it’s also something you can fix at the editing stage. In the Adobe Camera Raw editor, open your RAW file and select a preset option from the drop down list, or manually adjust the white balance setting using the Temperature and Tint sliders.
