Following is a compendium of Internet sites which have good Photoshop Tutorials. Take advantage of these. If you can discipline yourself to do a few of these tutorials every week, you will find your proficiency will escalate. I have also listed some sites where you can download free brushes, shapes, actions, etc. Be aware that these sites change frequently, and some may even disappear. So please forgive me if some of these links are not current. There are almost too many sites to visit, so here are some of my favorites. if you happen to find a link that isn't listed here, don't hesitate to send it to me, and I will post it here.
A good site, focussing on Photography.
