A number of posts in recent threads state that film has more dynamic
range than DSLR sensors. Actually, these measurements

( http://www.clarkvision.com/imagedetail/film.vs.digital.summary1.html ) clearly show the contrary, with slide film having about 5 stops dynamic range, print film about 7 and a DSLR getting to 10 stops. I would be interested in understanding on what are the statements about the low dynamic range of DSLRs based?

"slide film having about 5 stops dynamic range, print film about 7" - sounds more like a blanket statement. at what nominal ASA? exposed as what ASA? processed in what manner?

moreover, grain/noise character/structure is important to perception of dynamic range. equally important is color reproduction in shadows. measured DR may be much wider then perceived DR.
