Unsharp Mask works by increasing the contrast along the edges within an image. It first creates a blurred version of the original image. Then, this blurred image is subtracted from the original to create a mask of edges. Finally, this mask is added back onto the original image, enhancing the visibility of edges and details without affecting the overall image. This technique is a powerful tool for improving sharpness and detail in digital images, making it a popular choice in both photography and graphic design.
