onOne Software is a maker of Photoshop, Lightroom and Photoshop Elements plug-ins and a suite of programs that can add creative effects to your photos. For a short time you can download their Perfect Effects 8 program/plug-in for free. The link to do this is shown below.
This will get you the plug-in, as well as the standalone program. I have and use this plug-in and others in the onOne suite of programs/plug-ins and I really like them.
