how to do the Apple iPod advertisement?

I am trying to do some things like the Apple iPod advertisements:

http://www.apple.com/ipod/

or something like the guy with the camera in this ad:

I guess it is just taking a bit-map and turning into a vector image. Can you use photoshop or do you have to use illustrator. Any help would be greatly appreciated.
