Adobe products such as Photoshop, After Effects and Premiere are not intuitive to use, and commercial courses can be expensive. Adobe offers a series of tutorials on aspects of its products. To access these tutorials you will need to register. If you already have Adobe software and have registered online, you will automatically have access to this area provided you have the userid and password handy.
This area also includes downloads and other resources to improve your software use.
I looked at creating rollovers in Photoshop to see how this site works. The principles were clearly explained, in easy to follow steps with images to illustrate each point. The navigation was simple and I wasn't overwhelmed with too much detail. I also looked at Premiere. Tutorials for this package include Quicktime movies, which once loaded, provide excellent coverage of the topic.
If you are a heavy user of Adobe products, this is a good site to have access to.
