As a guy I can't tell the difference between sky blue and light blue so I can sympathize with my camera when it's having a hard time trying to accurately read the colors in a scene.
Since different sources of light have different color hues, a picture taken with a normal white balance under artificial lighting conditions are not accurately portrayed. To combat this we must manually change the white balance on the rear of our cameras.
Though the human eyes can automatically adjust to different lights and color temperatures to sense right color, a camera needs to be adjusted to different lights for accurate color reproduction. By adjusting the white balance setting of your digital camera, you can alter the required light or temperature to produce the most accurate colors in a digital image.
Auto – The Auto setting helps in adjusting the white balance automatically according to the different lighting conditions, but you can try other modes to get better results.
Tungsten – This mode is used for light under a little bulb like tungsten, and it is often used while shooting indoors. The tungsten setting of the digital camera cools down the color temperature in photos.
Fluorescent – This mode is used for getting brighter and warmer shots while compensating for cool shade of fluorescent light.
Daylight – This mode is for the normal day light setting, while shooting outdoors. Many cameras do not have the Daylight mode.
Cloudy – This mode is ideal for while shooting on a cloudy day. This is because it warms up the subject and surroundings and allows you to capture better shots.
Flash – The flash mode is required when there is inadequate lighting available. This mode helps pick the right White Balance under low light conditions.
Shade – A shaded location generally produces cooler or bluer pictures, hence you need to warm up the surroundings while shooting shaded objects.
