Learn about the concept of aberrations in optical systems. On photographs taken using a digital camera, very small highlights may frequently appear to have chromatic aberration where in fact the effect is because the highlight image is too small to stimulate all three color pixels, and so is recorded with an incorrect color. Chromatic aberration also affects black-and-white photography. iasLog("criterion : cdo_pc = dictionary"); var pbjs = pbjs || {}; some camera manufacturers employ lens-specific chromatic aberration appearance minimization techniques. Third party software tools such as PTLens are also capable of performing complex chromatic aberration appearance minimization with their large database of cameras and lens.

Chromatic aberration is also called colour fringing and is a fringing effect caused by the refraction of different wavelengths of light at slightly different angles than the norm that results in failure to focus all the colours to a single point in our case, the focal point.
