The Unsharp Mask is a popular image editing technique used to enhance the sharpness of photographs. Despite its name, it actually increases contrast along the edges of objects, making them appear more defined. This method works by creating a blurred version of the image and subtracting it from the original, which emphasizes the edges. This technique is commonly found in software like Adobe Photoshop and GIMP. Users can adjust parameters such as the amount, radius, and threshold to control the effect. Proper use of the Unsharp Mask can significantly improve image clarity without introducing excessive noise or artifacts.
