Well, don't think you learned something too fast. I may be wrong. I had heard of the technique, but just tried it myself on a typical image and found that it doesn't do too much for it until you use pretty heavy noise.
Far better, is to use a very light gaussian blur to the image.
So I stand totally corrected.
EDIT: It could be I'm doing the technique incorrectly. I was trying to add noise after the resizing. Maybe if you add it before the resizing you get less jaggies after resizing. I dunno. Looks like gaussian is a better way to go. |
FWIW, in PS 7.0/CS2/CS3beta I've found the 'History Brush' invaluable for proper sharpening and it's a regular part of my workflow (where challenge rules allow here, always otherwise).
After applying Smart Sharpen, USM, highpass or whatever sharpening technique you use, select the History Brush from the Tools palette, click the History palette and check the box next to the last step *prior* to sharpening, set Brush attributes to soft (0-15% works best for me, YMMV) and Opacity to 30% or so (different values work for different needs, as always) and "dilute" the effects of sharpening only in those areas where it was too much -- i.e., "jaggies" are evident. This essentially softens the impact of sharpening in those areas and is much less destructive to the rest of the image, and the sharpening effect itself, than the guassian blur method.
I also recommend making a copy of the base layer (whatever image layer you sharpened or will sharpen) since use of the History Brush isn't a non-destructive mask and is only reversable to the point your History list reflects it.
