If I have to mention site that really helps me with my Photoshop skills, I’ll say it’s PSDtuts+. From PSDtuts+ I learn many professional techniques in designing. Finally, this week I had my tutorial published there, not one but two! It’s a pleasure to contribute to the community that has helped me a lot since I know nothing about Photoshop.
Don’t forget to see the full tutorial. I hope they’re all usefull.
