The chief function of color should be to serve expression. ~ Henri Matisse
Have you ever taken a photo and found the results to have an unnatural color cast? You may be experiencing white balance issues.
White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the “color temperature” of a light source, which refers to the relative warmth or coolness of white light. Our eyes are very good at judging what is white under different light sources, but digital cameras often have great difficulty and can create unsightly blue, orange, or even green color casts. Understanding digital white balance can help you avoid these color casts, thereby improving your photos under a wider range of lighting conditions. I capture in RAW and use auto white balance (AWB) when on location and correct the white balance later in Adobe Lightroom. I’ve considered doing a custom white balance on location but find the temperature tends to change as the day progresses and I don’t have time to fiddle with it. In the studio under controlled lighting I do use a custom white balance setting.
Cambridge in Colour has a tutorial that will explain white balance in more depth if you are interested.
