>From what I have read, DMAX 4.0 is the theoretical limit or the >calculation scale, not the limit of a particular film.
The *theoretical* maximum DMAX depends on the bit depth of the scanner. For a 48-bit scanner, the theoretical maximum is 4.8, for a 36-bit scanner it's 3.6. How close the *actual* DMAX comes to achieving the theoretical maximum depends on the quality of the CCD and the associated analog circuitry. -- Mark Roberts www.robertstech.com - This message is from the Pentax-Discuss Mail List.
