002: American Cinematographer magazine, www.TheAsc.com.
Are you a camera nerd? Have you ever consulted a dept-of-field table? Do you own a light meter? Heck, do you even know what a light meter is? If you answered "yes" to any of these questions, American Cinematographer might be the magazine for you. Through interviews with directors of photography and other camera crew members, AC covers everything involved in getting an image from the real world to the silver screen, from the lights, lenses, cameras, and film stock used on the set to the processing and color timing in post-production.
American Cinematographer isn't the cheapest magazine around, but I think it's well worth the subscription price. If you want a free, in-depth sample, you can read many past magazine articles in their entirety at www.TheASC.com. For starters, check out these stories about Kubrick's Eyes Wide Shut and the original 1977 Star Wars.
