Sony Digital University is currently providing free acces to some great digital photography tutorials. An overview of the course I am currently enrolled for:
Digital Photography Made Simple
Learn more about using your digital camera to improve your photography skills and capture professional-quality digital photographs. If you don’t already have a digital camera, find out what you need to look for as you shop, and once you have your digital camera in hand, get good advice on how to take better digital pictures for a variety of uses, from professional marketing materials to a family photo album.
