ML previews are not JPEG, but uncompressed RGB. Maybe OS X only recognizes JPEG previews?

If anyone wants to polish his coding skills, try looking in chdk-dng around create_thumbnail. You'll probably need the libjpeg library.


Interestingly, when I use the new version of mlv dump on a 10.7.5 system, it generates thumbnails but when I bring over other DNG folders from a 10.9 system, no thumbnails are present.


I can't see .dng previews either and I'm on 10.8.5. Cdng works fine though. Let's see where this is headed..

There are thumbs already it seems only can, t be read in maverick.
I believe thomas is working on updating his cdng converter rawmagic for mac. That would solve your problem

is there any more news on this?
