Aberration

The blurring of a photographic image caused by improperly focusing the camera lens. A specific form of aberration is called chromatic aberration, a dispersion of colors that varies slightly from lens to lens. Chromatic aberration typically manifests itself as concentric rings of colors on the edge of an image. Keeping the lens curvature within strict tolerances can eliminate this problem. See also Newton's Rings and Achromat.
