I just did a couple of quick tests with PEF files generated by my *istDS. The PEF files are approx 10Mb in size.
Converting them to DNG (converter v2.4), with loseless comprerssion, reduces that to approx 6Mb. Converting them to PEF, but embedding the PEF, increases the size to approx 16Mb. Some of the metadata does seem to get lost, lens type, etc, but the basics like shutter, aperture, focal length & ISO do get preserved in the DNG format. I also like that I can rename the PEF files during the conversion. So 'IMG2500.PEF' can become 'Party050316_001.dng' (up to four fields can be specified), making future identifaction a little easier. Is the loss of some metadata worth a 40% reduction in storage costs ? Well I guess that's a decision each of us will make for ourselves. I think it is, but I'm still using CDR rather than DVD for my archiving. ---------------------------------------------------------------------- Fred Widall, Email: mailto:[EMAIL PROTECTED] URL: http://www.ist.uwaterloo.ca/~fwwidall ----------------------------------------------------------------------
