Chromatic aberration definition and meaning on Dictionary terms: noun Optics. the variation of either the focal length or the magnification of a lens system with different wavelengths of light, characterized by prismatic coloring at the edges of the optical image and color distortion within it.
Chromatic aberration meaning in Digital terms is An image defect caused when different wavelengths of light are focused at different distances from a lens. This results in varying degrees of sharp focus at the image sensor depending on the color or wavelength of light. Chromatic aberration is seen as "color fringing," and is most noticeable in an image at edges with high contrast.
