Here's a great video if you don't have a clue about digital photography. Come to think of it, it's a great review if you do know what you're doing. It's also great if you're shopping for a new digital camera.
The narrator does things like describing the auto landscape mode in terms of the f-stop (aperture opening)--saying that it's like shooting at f/8.
He uses a great camera too--a Canon A710*--with all the manual settings on a wheel at the top, just as you'd see in a dSLR camera.
Check it out, you'll be amazed at how much he goes over in 7 minutes.
