Another common issue is white balance, which tells your camera what true white is in your photo.

Sometimes the auto white balance doesn't work properly. If your "whites" don't look white, try a manual setting.

For daylight bulbs, use your camera’s “daylight” or “fluorescent” white balance setting. If you must use incandescent bulbs, set the white balance to “incandescent” or “tungsten” (sometimes called “indoor”). This will help remove the orange hue from your photos.

Some cameras have a custom white balance feature, allowing you to define “white” by taking a shot of your nice white background.
