Well you are free to hold that position but to me the output from the CCD has just been sampled and massaged to fit the 12 bit RAW profile optimally. We don't know the data depth in processing, we only know that the CCD is sampled with 22 bit data precision. The 12 bit RAW file is contains discrete RGB data sampled under a Bayer filter pattern so it has to undergo significant post processing for it to be even recognised as a colour image. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
