Chromatic aberration is a type of distortion in photography where colors are misaligned and create unwanted color fringes around the edges of objects in an image. This happens because different colors of light bend by different amounts as they pass through a lens, causing them to focus at different points. As a result, red, green, and blue light can appear as separate, blurred colors around high-contrast edges. Chromatic aberration can reduce image clarity and sharpness, but it can often be corrected or minimized using lens adjustments or post-processing techniques.
