There are ten options in [Preset]: [Auto], [Daylight], [Cloudy], [Shade], [Day light fluorescent], [Day white fluorescent], [Cool white fluorescent], [Warm white fluorescent], [Tungsten], and [Flash].
[Auto] is the same setting as auto white balance in the camera. Thus if you took pictures with auto white balance, color does not change.
If you accidentally set improper white balance in the camera, selecting [Auto] in this palette may improve the image.
[Daylight], [Cloudy], and [Shade] are for pictures taken outdoors in the daytime. Since the scattered light of the sun is more bluish than the direct sunlight, [Shade] is the most bluish as the light source, followed by [Cloudy] and [Daylight]. In other words, [Shade] images are compensated most orangish, followed again by [Cloudy] and [Daylight].
[Day light fluorescent], [Day white fluorescent], [Cool white fluorescent], [Warm white fluorescent], and [Tungsten] are for pictures taken indoors. As the color becomes reddish in this order, [Tungsten] images are compensated most bluish.
[Flash] is, of course, for flash pictures. Select this only when the picture is taken with flash.
It may be confusing because the color temperature changes in the opposite direction. Start adjustment from the nearest light source used when the picture was taken. If the image is reddish, select a light source with lower color temperature, and if bluish, select one with higher color temperature. In this way, find the nearest light source to your preference.
If you still cannot get your favorite result, select the nearest light source, then make fine adjustment using a slider below. Moving the slider toward minus makes the image bluish, and moving it toward plus makes it orangish.
