I've signed up for another short Photoshop workshop with Cynthia Powell, called "Collaged Illusions". Even though it's for beginners and I've been using Photoshop Elements for several years, I find that I always learn something invaluable in Cindy's workshops, and they are always lots of fun.
Having been self-taught in Photoshop, I often find that I have leaped ahead into some more advanced techniques, while having bypassed some of the basics. It's such a relief to find easier, faster ways to do some of the things that I've been unnecessarily struggling with.
