Use Unsharp Mask to emphasize edges and details in images.
This process is often referred to as "sharpening" an image. This lightens the image and gives it emphasis, but does not distort the colors.
If you add the IMQuery transformation to a policy, use the
im variable, and select Unsharp Mask, you can use a query string to sharpen any image using this policy. See Syntax and Examples for the syntax for the query string parameter.
