Sharpening increases contrast along image edges so transitions between subjects look clearer. Traditional unsharp masking compares each pixel with a blurred version and amplifies the difference. Amount, radius, and threshold control the effect. Too much sharpening creates visible halos and lowers image quality.\n\nLandscape photographers use sharpening to make foreground rocks, tree bark, and architectural details stand out. A sharp mountain scene shows defined ridges, snow texture, and crisp rock formations. Without sharpening, the same image can look slightly soft. Careful sharpening reveals natural detail without artifacts.\n\nAI sharpening improves traditional methods by understanding image content. It applies stronger sharpening to text, edges, and textures, and lighter or no sharpening to smooth areas such as sky, skin, or out-of-focus backgrounds. This avoids amplifying noise and handles slight camera-shake blur better.\n\nMagic Eraser's AI Enhance applies intelligent sharpening in its enhancement pipeline. The AI chooses which regions need sharpening and applies suitable levels. Portraits keep natural skin while eyes, hair, and clothing become clearer; landscapes gain texture in rocks and foliage without harsh artifacts in sky areas.
