Chromatic aberration effect6/22/2023 ![]() ![]() This is known as chromatic aberration.īecause lenses are made with different materials, lenses can be ground to have different shapes and curvatures that can cause different amounts of chromatic aberration.īecause lenses are made using glass and plastic, they can be ground differently to correct for this distortion. But as the light passes through the lens, it changes direction.Īs shown in the diagram to the right, when rays of white light pass through a lens, they bend slightly toward the blue end of the spectrum. As light passes from air to glass, it continues on as if it were in air. A lens consists of two surfaces, one for convex and one for concave. What Is Chromatic Aberration?Ĭhromatic aberration is an optical phenomenon that occurs when light travels through a lens. In some cases, such as using an ultra-wide angle lens on a full frame camera, you will be able to see chromatic aberrations even if they are not visible on your screen. These glasses may have different properties and thus cause different types of chromatic aberrations. The problem with this is that most cameras use different types of glass for different purposes. ![]() This interference causes them to cancel out each other when they come into contact with each other, causing an area where they all cancel out instead of being mixed together.Ĭhromatic aberration occurs in lenses that are made from glass and are used to focus images onto a sensor. The waves are different colors, and they have different wavelengths, which means that they interfere with each other differently depending on their color. The color fringing around the edge of an image is caused by waves of light being reflected off the surface of an object and interfering with each other. The effect can be reduced by using a well-calibrated lens and by adjusting the aperture setting. This effect can be seen at the edges of the focus point, as well as in the center.
