Värihajonta
Värihajonta, known in English as chromatic aberration, is an optical phenomenon that occurs when a lens fails to focus all colors of light at the same convergence point. This is due to the fact that a lens refracts, or bends, different wavelengths of light by slightly different amounts. This dispersion of light causes colors to "fringe" or appear as halos around objects, especially in high-contrast areas.
There are two main types of chromatic aberration: longitudinal and transverse. Longitudinal chromatic aberration occurs when
Chromatic aberration is a common issue in simple lens systems and can be reduced or eliminated through
