New Sharpening Routines
(for D800E with no ACR capture sharpening)
Edge Sharpening (at original size before outputting)
Duplicate Green channel,
rename as Edge Mask
Stylize-> Find Edges
Noise -> Median Filter, size 3
Image -> Adjustments -> Levels to darken the edges: something like 150, 1.0, 245? (just inside the lefthand edge of the arc)
Gaussian Blur 2 pixels
Apply to new layer (luminosity), opacity 66%
adjust layer opacity to taste.
[Optional: add another layer of masked-in USM 500/1.0/0 for areas that require special attention]
Combo USM/High Pass for final output sharpening once pre-sharpened images have been resized for output, for printing or for web
Flatten image and resize to output.
New layer with opacity 66%, USM 100/1.0/4
Edit–>Fade 50% (Luminosity) (65% for 1200pix)
High Pass radius 2 (or 0.5 for web)
check at 50% (or 100% for web) and alter layer opacity to suit (100% for fine detail macro 1200px, layer duplicated even, up to 2x + 1@66%)
This works very well and leaves far fewer processing artefacts than my previous routines. It is, of course, quite involved and requires quite a bit of Photoshop knowledge.
