imago features a quick, one-click Sharpening filtering effect to enhance the clarity (apparent sharpness) of an image. It sharpens and enhances edges by subtracting a blurred version of the image (the unsharp mask) from the original. The unsharp mask is created by Gaussian blurring the original image and then multiplying by the "mask weight" parameter (default value used: 0.2).
