Query: excellent DVD tutorial!!!

An excellent DVD for understanding the Canon EOS Camera especially when upgrading from a less expensive camera to one such as this. Great tutorial for use of all features and Options on the camera. Especially in use of opening aperture and shutter speed. Easy to understand chapters with a menu based navigation so I can go back to each beginning. I am better understanding the ISO option. It was well worth my money. The cost of a class to learn the principles of digital photography is small verses the cost of a similar class, and I learn about my very own camera, not another model. I also get to rewatch the DVD when I choose to.
