WebbSharpening is very specific to output, so it should be the last thing you do in a filtering workflow. Sharpening filters are very sensitive to noise. You should always apply noise reduction first, if necessary. Choosing the correct radius is critical for obtaining good results as sharpening may create unwanted edge effects or increase image noise. WebbThe filter works by identifying sharp edge boundaries in the image, such as the edge between a subject and a background of a contrasting color, and increasing the image contrast in the area immediately around the edge.
