Chromatic aberration, also known as color fringing, is a color distortion that creates an outline of unwanted color along the edges of objects in a photograph. … Each type of aberration causes different colors of outlines along an object’s edge.
What does chromatic aberration do?
Chromatic aberration is an effect that occurs when a lens is not able to properly refract all the wavelengths of colour in the same point. It’s quite a common problem in photography that affects almost all lenses, though high-quality lenses will present with less chromatic aberration compared to lower-quality ones.

Can chromatic aberration be corrected?
To correct chromatic aberration, achromatic or apochromatic lenses or lens groups are used. Sophisticated design and optimisation software has made possible the design of highly-corrected optical systems, but high machining accuracies and close tolerances are required in manufacture.
Why is chromatic aberration bad?
Chromatic aberration (also known as color fringing or dispersion) is a common problem in lenses that occurs when colors are incorrectly refracted (bent) by the lens; this results in a mismatch at the focal point where the colors do not combine as they should.
Is chromatic aberration normal?
Chromatic aberration, also known as “color fringing” or “purple fringing”, is a common optical problem that occurs when a lens is either unable to bring all wavelengths of color to the same focal plane, and/or when wavelengths of color are focused at different positions in the focal plane.

What does remove chromatic aberration mean?
Chromatic aberration is a phenomenon caused by distortion of the lens. Basically, it is a failure of the lens to focus all the colors to the same convergence point. The effect can be generally seen in dark edges adjacent to bright areas of an image; it looks like an out-of-focus ghost of magenta or purple color.
