Perhaps the most infamous match occurred recently, when Heather Champ faced off against Derek Powazek. For the seventh volley, Powazek tried something new. Rather than manipulating the image with Photoshop, he printed it out, crumpled up the printout, ran outside his place in San Francisco, stapled the printout to a telephone pole, photographed it, and sent Champ the digital photo as his next volley.
In response, Champ added to the image a map from MapQuest pinpointing the spot where Powazek stapled the poster outside.
"That was the best volley in Photoshop Tennis history," Coudal said.
