Chromatic Aberration
These sliders are designed to get rid of color fringing that often appears on the edge of high contrast objects (Figures 16.121 and 16.122). This fringing is caused by light being bent as it passes through the elements that make up a camera lens, which causes the light to bend and separate much like white light turns into a rainbow of color when its sent through a prism. You won't see this fringing on every image and you'll only be able to notice it when you zoom in to 100% view. These same two sliders are also available in the Camera Raw dialog box as is the next feature—Vignetting.
