No Fred, I should try those scripts. Sharpedge has more of an effect on Lena's eyes (perhaps too much) and in some cases increases noise. Gaussianedge seems milder but still very noticeable. I am pleased with adaptive-sharpen, which is a big improvement over unsharp(mask). Adaptive seems to have ...

A radius(?) higher than 2 looks oversharpened to me, and ...
