About this document
Unsharp Mask and Blur Filters Guide by martarocacreus is a document available to read on EtoBox.
The Unsharp Mask filter is used to sharpen images in Photoshop by increasing contrast along edges. It works by making lighter pixels lighter and darker pixels darker near edges defined by a threshold. Over-sharpening can cause halos. Blur filters smooth transitions between pixels by averaging values, softening hard edges. Common blur filters include Gaussian Blur, Lens Blur, and Surface Blur, which preserve edges through a threshold.
