Free – and Open Source Clip Art. Not only are they free in the public domain and usable for any purpose whatsoever, but there’s also a cool collaborative environment in which you can make your own alterations and share them. A great graphics resource, and an excellent way to get involved in the practical design of these images.

Russell Brown (www.russellbrown.com) has created a really good tutorial on how to use the History Paintbrush in Photoshop.

Those of you who’ve taken my Photoshop classes know that I don’t often teach this tool. I actually think it’s an awesome tool – but of course I’m ALL about non-destructive techniques, and this isn’t one of them. This technique changes original pixels permanently (there are work-arounds, but they’re rather indirect). So, I recommend knowing how this tool works, what you can do with it, and then knowing you can use it for more of your “quick and dirty” retouching and repair needs.

Very cool website to download some common, and not-so-common symbol and image graphics, all organized and searchable. Most images are open source and usable by anyone, some are copyrighted. Please check before use.
