Sharpen options
|
Amount |
Specifies the amount of light added to or removed from each edge. Higher values produce darker edges. |
|
Radius |
Specifies the number of pixels to adjust around each edge. Higher values increase the number of sharpened pixels. |
|
Threshold |
Specifies how different the lightness values of two adjacent pixels must be before they are sharpened. Higher values increase the required difference. It is recommended that you set the threshold so that it enhances edges while keeping background noise to a minimum. |
|
Threshold Feathering |
Select this option to create smoother transitions between sharpened and unsharpened pixels. If this option is not selected, you may see lines between pixels that have been sharpened and pixels that have not been sharpened. |
