I little bit of both I think :-) It is a software limitation since nobody has bothered implementing it. It would be possible to make software that writes data files in any of the (documented/understood) RAW camera formats like the Pentax PEF files, or Adobe's DNG which is sort of generic 'RAW'. However, since the conversion to the initial format (TIFF, JPG) has actually REMOVED information from what was originally in a RAW file you will never get that back. So a conversion from RAW to JPG to RAW can never be lossles. Regards, JvW ------------------------------------------------------------------ Jan van Wijk; http://www.dfsee.com/gallery
