Yes I know, but I was just referring to the pointlessness of doing
that. 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.
