I don't know if there's anything turn-key that can do it (especially if there's a problem with the DNG file). What, precisely, do you mean by "the DNG file is lost, but the preview jpg is still intact"? If the DNG file is present (but unreadable) and you can see a preview image, it's quite likely that you are looking at a cached preview image that your file browser has created, rather than actually reading the jpg preview from the DNG file. (You can test this by copying the DNG file to a new location, then pointing your file browser at that new image location; if you can see a preview image then there's enough of the DNG file left intact to be able to get at the embedded jpg). If you can't even read the DNG file, then you're going to be limited to whatever preview image your file browser created. That's likely to be at much lower resolution than the original DNG (on Windows 10, for example, the maximum dimension is limited to 256 - I don't know about Macs). If you can get at the DNG file, though, you should be able to get the preview jpg embedded in the file, which is going to be much larger. It used to be the same size as the full image, but I haven't actually dug inside a Pentax image file since they switched from TIFF/PEF to DNG. -- %(real_name)s Pentax-Discuss Mail List To unsubscribe send an email to [email protected] to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
