Environmental shot of White Eared bulbul. Shots in shaded areas always introduces a color cast. In Canon with auto white balance it introduces a blue cast leading to a color shift. Though I would like to keep the white balance constant and not disturb it at all times when auto white balance gives incorrect result have to manually adjust it while processing. This is also the advantage of shooting in raw. It it not possible to change white balance during processing in a straight forward way if you are shooting jpeg.
