Once upon a time, photographers shot with something called film, and telephones were for talking on, not taking pictures with. Before digital photography flashed onto the scene, capturing images meant trekking to the store to buy film or flash cubes and even hand-printing photographs in a darkroom. From oatmeal-box pinhole cameras to Holgas to Kodak Ponies and Poloroid Land Cameras, the evolution of photography equipment has been as rapid and varied as the subject matter it preserves, and almost as likely to get lost in the progression toward the future. Luckily, the Dallas Public Library is helping curate an exhibit entitled Got Film? Classic Photographic Equipment of the 20th Century, which showcases early cameras, film and negatives. "It includes things that the library owns and things that are being brought out by collectors," said exhibit curator Andrew Anderson. "In addition to cameras, we're going to have tintypes, a daguerreotype and glass plate negatives." Sounds like an interesting development to us. Got Film? is on view through May 30 on the fourth floor of the J.
