- Sharpening
- Before printing it is a good idea to do some sharpening
- Settings for USM
- The "Unsharp Mask" is the only filter you need
- Amount - Controls the intensity of the sharpening (120% - 200%)
- Radius - Width of the sharpening effect. Wider radius more emphasis on edges ( 1 - 2)
- Threshold - Which pixels will be sharpened. Higher Threshold less sharpening (image dependent)
- Edge Mask Technique
- Duplicate Green channel and name "Edge Mask"
- Filter -> Find Edges
- Median Filter -> about 1-3
- Use Levels to darken edges
- Run Gaussian Blur to soften edges (1.5-3)
- Images -> Adjustments -> Invert
- Command - J to create a new layer
- Blending -> Luminosity and Opacity to about 66%
- Now run USM this time Threshold can be 0
- Sharpening Brush - Localize Sharpening
- Duplicate Layer
- Set Blend Luminosity and Opactiy to 66%
- Run USM - set pretty strong focusing on target area
- Layer Mask -> Hide All
- Large soft brush lower hardness
- White brush "paints" sharpening, Black "undo"
- Much more to sharpening than meets the eye
