It’s not uncommon for an otherwise good photo to have a color cast—that is, to have all its tonal values shifted so it’s too blue, like Figure 7-14, or too orange.
Figure 7-14. Left: You may wind up with photos like this every once in a while if you forget to change your camera’s white balance—a special setting for the type of lighting conditions you’re shooting in (common settings are daylight, fluorescent, and so on). This is an outdoor photo taken with the camera set for tungsten indoor lighting. Right: Elements fixes that wicked color cast in a jiffy. The photo still needs other adjustments, but the color is back in the right ballpark.
