| Re: What exactly is pixel radius? If you are referring to the Unsharp Mask Filter, the radius represents the number of pixels along the width of an edge to which the contrast increase is applied to. The Threshold is the amount of tone values that pixels must differ from each other before any contrast is applied. Regards, Murray  |
