Chromatic Aberration Chromatic aberration is an optical phenomenon that causes different wavelengths of light to focus at slightly different points, resulting in color fringing or distortion around the edges of objects in an image. It occurs when light passes through a lens and is refracted unequally, causing colors to separate into their spectral components.
Chromatic aberration is most noticeable in high-contrast areas of an image, such as the edges of objects against a bright background, where it appears as colored fringes, typically purple or green in color. It can occur in both lenses and digital sensors and is more pronounced in lower-quality lenses or when shooting at wider apertures. Correcting chromatic aberration often involves using lens corrections in post-processing software or employing specialized lenses designed to minimize aberrations. |
