Computer LCD - 9.5 - 700:1
DSLR camera (Canon EOS-1D Mark II) - 11 - 2048:1
Print film - 7 - 128:1
High-dynamic-range photographs are generally achieved by capturing multiple standard photographs, often using exposure bracketing, and then merging them into an HDR image. Digital photographs are often encoded in a camera's raw image format, because 8 bit JPEG encoding doesn't offer enough values to allow fine transitions (and also introduces undesirable effects due to the lossy compression).
