I've downloaded Dave's Sharpening Actions (a zip file containing one .atn file), and I'd love to try the High Pass Sharpening action mentioned by Rick; but I can't work out how to install it in Photoshop Elements 7.0.
The instructions that I found on the web - for example, this one - mention an accompanying .png file, which is not provided in Dave's Sharpening Actions. The file structure in the article is different to mine too.
Has anyone tried installing actions in Photoshop Elements 7? Would you help me understand how to do it?
