Unsharp Masking

Unsharp masking is a digital image processing technique used to enhance the sharpness and clarity of an image. Despite its name, the process actually sharpens the image by increasing the contrast along the edges. This technique is widely used in photography, graphic design, and printing to improve the visual detail and overall quality of images.
