Digital Camera White Balance Secret Revealed: Leaving you digital camera white balance set to ‘auto’ can be a big mistake and may result in disappointing results according to editors at DCMag.
Digital cameras, though, can compensate for different-colored lighting by altering the ratios of red, green and blue as the image is processed and saved.

Auto vs Preset
You shouldn’t leave your camera set to auto white balance permanently because it won’t always get it right. The camera will attempt to analyse the colours in the scene and ‘normalise’ them, but it can often fail to differentiate between the colour of the light and the intrinsic colours in the subject itself. In addition to this, it may attempt to compensate for atmospheric lighting conditions early or late in the day that are actually part of what you’re trying to record. Finally, where you do want to ‘normalise’ the colours, you’ll find that auto white balance systems usually fail to compensate for extremes of lighting, like the excessive warmth of domestic tungsten lighting or the pronounced ‘coldness’ of the light in deep shade. Indeed, you may find it better to choose your white balance settings manually to suit the conditions, because at least then you’ll know how the camera is going to respond.
