Photoshop plug in's?

Cnet is a 'warehouse' for all kinds of software which I have found reliable in the past. Redfield plug ins do quite a lot which can create some amazing effects and they do have some free software. And as Dave has mentioned, Topaz but not free. Their software will work with Photoshop but they have recently created their own host programme called Studio and some of their plug-ins are geared to working within that set-up. Also with some free stuff, Flaming Pear, which has some with really good effects. With all of these downloads make sure you put your security code in a safe place as they will not allow you to use it if for instance your computer dies and the new one doesn't have the security code needed for the software to function. Good luck and enjoy.
