DSLR cameras are showing 10 stops or more of dynamic range, which is about 3 stops more than that of print film, probably 5 stops more range than slide film. Quoting Roger Clark (http://www.clarkvision.com/imagedetail/film.vs.digital.summary1.html): "There seems to be an urban legend that says digital cameras have less dynamic range than film. The legend is wrong. ...... The slide film records only about 5 photographic stops of information (a stop is a factor of 2, so 5 stops is 32). The print film shows about 7 stops of information. The digital camera shows at least 10 stops of information (this test was limited to 10 stops). Other tests show the Canon 1D Mark II camera has about 11.6 stops of information (a range of 3100 in intensity). Other DSLR cameras, like the Canon 10D have around 11 stops. " The better DSLR exists already. William Robb -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
