there are two definitions of dynamic range, one that is the maximum value represented in the system, determined by the number of bits, and the total brightness range, which is independent of the number of bits. you and others are using the term without specifing in advance which meaning you intend. scanner manufacturers specify the first. more bits means the maximum number you can represent is higher and so you can resolve shadow detail better. no scanner manufacturer i know of specifies the second. when Rob Studdert and i talk about dynamic range of digital cameras and you talk about the dynamic range of film, we are talking about the second.
