Time to play with David Clunas =)

The Game:

Photoshop tennis is a competitive activity that has evolved on the
Internet utilising Corel Paint Shop Pro, Adobe Photoshop, or similar
bitmap graphics editors. It is normally a game for 2 players, though
doubles matches and any number of players are theoretically possible.
The players pick a starting image, then one player makes some sort of
alteration to the image in any graphics manipulation package that they
like. They then send their altered image, usually via email (though posting
the image to a Photoshop tennis forum is another possibility), to the other
player, who then edits that image and sends it back to the first player.
This process goes back and forth until the number of rounds that they have
previously decided on are over. When the final round is over, an independent
judge determines who played the best shots, and declares that person the winner.
Sometimes extra rules can be enforced such as sticking to a particular software
package, or keeping the images to a theme.

The Players:

Linda Matta Vs. David Clunas
