Achieving Natural Color (White Balance)

The source of incident light on the subject affects color. For example, the same sheet of white paper held under sunlight may appear tinged with red when held under an incandescent light. Because the human eye adapts to the colors of source light, it perceives the sheet as white in both cases. White balance adjustment attempts to reproduce colors naturally so images are not affected by surrounding light. With a camera that uses film, you could purchase film suited for reproducing color under different light sources and adapt to shooting conditions by using filters. Similarly, with a digital camera you have the option of adjusting the white balance.

There are three ways to adjust white balance with this camera.

Auto white balance

The camera automatically determines the amount of white light and adjusts the color balance. Auto white balancing is sufficient for most conditions, but if there is no near white color in the picture, colors that are not originally white may appear white in the image and the white balance of the image may not be correct. In such a case, use a white surface and quick reference white balance to achieve the correct white balance, or use preset white balance to select a color temperature for the incident light to achieve the correct white balance.

Quick reference white balance

You select an object like a white wall or a piece of white paper to be used as the white base to balance color in your picture before shooting. Just point the camera at a sheet of white paper and press the white balance mode buttonto set the white base for balancing color in the picture. The setting that you capture is saved as a “preset” white balance setting and recorded in the camera's color temperature selections.

Preset white balance

You select a color temperature setting appropriate for the light source. For example, use preset white balancing when you want to reproduce more red in a picture of a sunset, or capture a warmer artistic effect under artificial lighting. By experimenting with different preset white balancing settings, you can achieve a variety of pleasing color effects in your pictures.
