Chromatic aberration is a visual distortion that occurs when a lens fails to focus all colors of light at the same point. This phenomenon happens because different wavelengths of light bend at different angles when passing through a lens, leading to color fringing around the edges of objects in an image. It is most noticeable in high-contrast scenes, where bright colors can appear blurred or misaligned. This optical issue is common in photography and can affect images taken with cameras, including those in smartphones. To reduce chromatic aberration, photographers often use specialized lenses or post-processing software to correct the color distortions, enhancing the overall quality of the image.
