Nowadays, digital cameras offer photography enthusiasts enough flexibility for colour shifts in different lighting conditions by adjusting the white balance. If you have a digital camera, better learn and use the art of white balancing for better pictures.
This setting allows you to compensate for the colour differences in different types of light conditions. In other words, it can make the colours warmer or cooler to match the intended mood or demand for natural colours in your photograph. Once you know how to use it, you'll be amazed to note about the difference, it can make to photographs.
If white balance is not present, a subject in the shade is slightly bluer than the same subject in bright daylight and incandescent light bulbs has orange shades as compared to both. The setting compensates for the colour conditions under which the subject is being photographed.
Since the white balance setting differs from camera to camera, so read the manual of your camera to find its control on the camera. For this hit the 'menu' to find the setting 'white balance or WB' and once again, press the button and choose which white balance you would want to use. Better try shooting in a semi-automatic exposure mode, like ‘Program’ to handle the camera as photography-literate person.
Also, try your "Daylight", "Cloud" and "Shady" white balance settings under daylight to experiment with and find out how these choices affect the picture. The latter two will give warm colours and use of white balance will trim the colours to give your picture natural shades.
Under the indoor lighting and at the sunset time your camera produces a little cooler effect. You can then go for "hue adjustment" if it is available on the camera. It also needs to be understood that white balance control cannot correct for some light sources like sodium lighting.
Though the auto white balance control on a digital camera adjusts the white balance automatically to different light colours, or temperatures, but it is always good to set it yourself to master the art of photography. And more so in the landscape photography, the white balance should be pre-set for preserving the natural colours of the light precisely to give the shot its character.
