Re: [Digital BW] help -- edge sharpening and Roark curves

2004-04-28 by Stephen Kobrin

Thanks Daniel,

It must be the hidden slection which I had forgotten about as I 
flattened the image before sharpening.  One of the last steps in the 
edge sharpening workflow I used was to hide the slection -- "hide 
edges."  

By the way, I used the edge sharpening workflow found at 
www.bythom.com/sharpening.htm.  While it is the first I have tried, 
it worked quite well and using levels it is easy to control what is 
sharpened and what is not.
