1. Have you tried reconverting such a DNG file with the DNG converter? Yes, it does accept DNG files as input as well.
2. What about posting such an "unusable" DNG file? Use yousendit.com if you don't have web space.
Thank you for your reply and offer to look into this issue. I have a 13 MB file from a Canon 5D. Exactly how (or whom) would I send that to so it could be shared in this forum. I would gladly do it via yousendit if I knew the process.
I know it does help find a solution, but I have run across some older DNG's that will open in LR 2 but will not open in Bridge/CSR 4. (These are DNG's created by Scott Kelby for his LR 2 book - I have attached on to this post.) I can open them first in LR and then tell LR to edit the image in Photoshop and it will open. I have not yet had the issue of LR not being able to open the DNG correctly. However, I may not have done a DNG conversion since I installed the 5.6 upgrade. When I get a chance I will go convert some CR2 files and see what happens.
I have uploaded one of Kelby's dng's that will not open in my desktop nor laptop Bridge/CSR 4 w/all updates. DNG 5.6 is unable to process them as well. It will import into LR. Other than that I cannot cause DNG's not to load into Bridge/CSR.
Opps the file is too big. You can download it from here. Kelby's Technical Copy Editor told me she did not have the same problem. Weird. I hope you solve your problem.
