Aliasing is a digital imaging effect that occurs when an image is composed of square pixels and the resolution is too low to accurately represent fine details. This results in a rough, step-like appearance along diagonal or curved edges, often referred to as a “jagged” effect. Aliasing is most noticeable on lines, text, or geometric patterns and can reduce image clarity and perceived sharpness. Photographers and digital artists use techniques such as anti-aliasing, higher-resolution capture, or post-processing software to smooth these edges and improve overall image quality. Understanding aliasing is important for digital photography, graphic design, and any application where precise visual representation is critical.
