This is not a photo that I took. This is actually an image by Brian Matiash (visit his blog at brianmatiash.com/blog/). HDR tennis is a facebook group started by Dave Wilson (visit his blog at blog.webartz.net/). HDR tennis is a weekly game where one of the artists submits several exposures of one of their images for the rest of the group to produce a HDR image. The group then critiques these images and votes on the best. Visit the facebook group at www.facebook.com/hdrtennis.
