LOS ANGELES In August, the people behind LA Photo Party will introduce an event photography concept called Photosphere that takes 360-degree photos and prints them instantly on site. As many as 30 guests can fit into a tent structure and be captured in a single photo at the same time. Costumes and props are available, and a team from Photosphere can rouse guests' energy and direct the shots. In addition to prints, photos are turned into interactive online movies that can easily be linked to Facebook, MySpace, or emailed—to proliferate a brand message well beyond event day. The cost of the setup varies depending on details like custom tents, sets, and logos, but prices start at $2,000.
