well previously I was using amount =300 and radius of .5, then when resized to 600 pix at widest edge, I was sharpening at about 75 and .5, but I was getting frustrated with the thick edges, so I changed my first amount to 500 and .3, then 125 and .3 when resized, i believe. either that or .2. one of the two
thanks for the comments everyone. the first image isn't popping as much as I want it to, so I'm going to work on it quickly and repost. check back in a minute.
