I have no problem with the *image* part of the PEF file format, since it's based on an open standard (TIFF, albeit slightly hacked to allow for 12-bit integers, etc). I don't like the proprietary tags in there that contain unknown (and potentially useful) information. Building a PEF->DNG utility using libtiff doesn't address that problem.
Also, I don't know why you'd need dcraw... that does the interpolation from a Bayer RAW to an RGB. Aside from embedded thumbnails, that wouldn't be necessary to go to DNG. Don't get me wrong... I think that going to DNG is a good direction to be going (directly out of the camera). Converting to it in an open-source environment doesn't make much sense, though. -Cory -- ************************************************************************* * Cory Papenfuss, Ph.D., PPSEL-IA * * Electrical Engineering * * Virginia Polytechnic Institute and State University * ************************************************************************* -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
