Jon Cassar: A lot of us that are in the film and television business are photographers -- maybe not professional, but avid amateurs. Myself, Michael Klick, and certainly Rodney Charters, our director of photography, are absolute photo hounds. We're so used to showing each other pictures from the set. At one point I thought, "Wow, there are a lot of good photos here," so I put them together into one of those Apple iPhoto books and sent it to Palace Press in the Bay Area. They loved what they saw and decided to make the book 24: Behind the Scenes, incorporating seasons one through five. It was a compilation of images from anyone who had a good photo, though most of the book is made up of photographs by Isabella Vosmikova, who was the set photographer at the time, as well as pictures by Rodney, and me. The pictures are not just behind-the-scenes snapshots or historical documents of what took place over the first five seasons; they had to have artistic merit as photographs.
