How is chromatic aberration reduced?

In the earliest uses of lenses, chromatic aberration was reduced by increasing the focal length of the lens where possible. … It can be further minimized by using an achromatic lens or achromat, in which materials with differing dispersion are assembled together to form a compound lens.

What does it mean to remove chromatic aberration?

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.

Does sunlight cause chromatic aberration?

Chromatic aberration is caused by dispersion. Have you ever focused a beam of sunlight through a prism to create a rainbow? Well, think of your camera lens as a prism. Light enters through one side and imperfections in the lens cause it to bend unevenly, separating the wavelengths.

In other words, different colors of light pass through a lens at different speeds, similar to how a prism separates white light into a rainbow.

Commonly advocated methods of avoiding purple fringing include:

  1. Avoid shooting with a wide-open lens in high contrast scenes.
  2. Avoid overexposing highlights (e.g. specular reflections and bright sky behind dark objects)
