Photoshop Tennis (sometimes known as Layer Tennis due to Adobe's attempts to discourage use of the term photoshop in a generic context) is not a competition but a game that is played between two competitors. A starting image is selected. Player One makes an alteration to the picture and 'serves' it to Player Two. Player Two makes an alteration and serves it back. The game continues until the players wish to retire.
