Turning the tables on stars like Ruben Studdard, the ''O.C.'''s Mischa Barton, and Ian McKellen (above), we handed 12 celebs a Nikon Coolpix 3100 digital camera (provided by the company) and said, ''Show us your summer.''

Whether they worked behind the lens or let a friend get the shot, their pix will help raise funds for the VH1 Save the Music Foundation -- which promotes music education in public schools. Place your bids in our third annual online auction for selected images (and other merchandise), and browse through our gallery to find out which celebs do well with a long shot.
