Not necessarily equivalent, but reduced noise certainly could be the *result* of increased dynamic range: Increased bit depth could conceivably facilitate the use of more advanced noise reduction algorithms that do more noise reduction with less damage to fine detail in the image. >Maybe they are able to utilize all of the 16bit depth of the RAW format. This isn't Pentax, but NuCore has apparently done it: http://www.nucoretech.com/nu3/10_company/corp_backgrounder.html#products -- Mark Roberts Photography & Multimedia www.robertstech.com 412-687-2835 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
