Chromatic Aberration – What It Is And How To Fix It
WebChromatic aberration is a phenomenon in which light rays passing through a lens focus at different points, depending on their wavelength. There … There are two types of chromatic aberration: axial (longitudinal), and transverse (lateral). Axial aberration occurs when different wavelengths of light are focused at different distances from the lens (focus shift). Longitudinal aberration is typical at long focal lengths. Transverse aberration occurs when different … See more In optics, chromatic aberration (CA), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point. It is caused by dispersion: the refractive index of the lens elements … See more In some circumstances, it is possible to correct some of the effects of chromatic aberration in digital post-processing. However, in real-world circumstances, chromatic aberration results in permanent loss of some image detail. Detailed knowledge of the … See more Chromatic aberration also affects electron microscopy, although instead of different colors having different focal points, different electron … See more • Methods to correct chromatic aberrations in lens design • Explanation of chromatic aberration by Paul van Walree • PanoTools Wiki article about chromatic aberration • Use in video games See more In the earliest uses of lenses, chromatic aberration was reduced by increasing the focal length of the lens where possible. For example, this could result in extremely long telescopes such as the very long aerial telescopes of the 17th century. Isaac Newton's … See more The term "purple fringing" is commonly used in photography, although not all purple fringing can be attributed to chromatic aberration. Similar colored fringing around highlights may also be caused by lens flare. Colored fringing around highlights or … See more nafed function
