1. About the Unsharp Mask Effect
The unsharp mask effect is a filter used to enhance the sharpness of an image. It works by increasing the contrast along the edges within the image, making details appear more defined and crisp. It uses a blurred version of the negative of the image to determine which areas to enhance, effectively sharpening the image without introducing excessive noise.
2. How the Unsharp Mask Effect Works
The unsharp mask effect works by creating a blurred version of the image and then subtracting it from the original image to detect edges. The detected edges are then enhanced by increasing the contrast along them, which makes the image appear sharper.
