The Unsharp Mask Filter or the Smart Sharpen Filter.
In photoshop, these two filters are used for better
control when sharpening your images. Sharpening helps make images crisp and
clear by enhancing the definition of edges in an image. Using Smart Sharpen
filter ensures you use some sharpening tools not available with the Unsharp
mask filter. Unsharp mask filter, on the
other hand, increases contrast along the edges of an image.
