Some free Photoshop plugins I find useful

[Fumesucker]

I use a couple of the plugins here quite often, Local Contrast Enhancement gives a nice sharpening and overall detail enhancement effect while avoiding some of the problematic artifacts associated with the usual sharpening algorithms such as Unsharp Masking. I've also employed the High Pass Sharpening plugin and the Selective Saturation plugin to good effect. I'm using a truly ancient version of Paintshop Pro and these plugins work fine with that, I suspect they will work with almost any image manipulation program that will accept Photoshop .8bf plugins.

1. Not a bad list of plug-ins.

However, most of that stuff is included in the current versions of most editors.

PaintShop Pro is good stuff, even after Corel bought it.
