> I've never seen any scanner use Dmax as a spec ... The Leafscan 45 has listed right in their brochure, and I quote: "Dynamic range: 5000:1 or 3.7 Dmax" So, obviously at least one manufacturer does use Dmax as a spec, and I am sure others do also. > the > ability of measuring Dmax - Dmin, are also absolute terms. Dmax, > historically, has always been an absolute term ... my point being > claiming it is a relative term, no matter the context, is a mis-use > and confusing application of the term. The pixel values (for which the range of is the theoretically highest Dmax for the scanner) are relative to each other, not absolute, in the systems we are talking about. You can not say one pixel value is differentiated from another by N volts without knowing what the voltage range is. The voltage ranges in different systems vary, and yet they can have the same Dmax. In fact, the voltage range is irrelevant, and the only thing that is relevant is the Dmax, or dynamic range or what ever you want to call it...
