Full auto mode is a shooting / exposure mode found on most cameras. In this mode the camera decides all the settings for you, and all you have to do is point and shoot. While it can often produce decent results, the fully automatic nature of the mode means that you can't make any corrections when the camera gets it wrong.

In this article I'll cover a bit about how full auto mode works, the various problems you can have with it, and when it can actually be a good shooting mode to use.

Different light sources produce light with different colors. For example, fluorescent lighting often has a green tinge, while tungsten lighting is a warm amber. Our eyes don't tend to notice the color of light too much, as they automatically correct for any color casts to a certain degree.

But a camera records what it sees, and this is where setting the correct white balance becomes important. If your camera is set to daylight color white balance, then you shoot under tungsten lighting, you'll find the resulting images have a strong orange color cast.

When you set the correct white balance setting on the camera, it modifies the camera's color response. It works in much the same way as using the curves tool in Photoshop to adjust color. The white balance setting determines the overall balance of colors in an image, to result in an image with a neutral color cast.
