Hi, you cannot use Bridge. The options are:
- ACR - validate the image(s) currently opened in ACR
- Adobe DNG converter - you can check an entire folder by reconverting them to DNG - free
- Lightroom - Perhaps the best option, but you need the licence as in ACR
Now some observations:
The idea behind DNG validation is that a checksum of the original image portion of the file, the one that should never change, is calculated when creating the DNG and stored inside it. What validation does is to recalculate this checksum from the image bits and compare it to the original checksum.
It is important to note that DNGs created outside of the Adobe environment, may not contain this original checksum. This happens with many in-camera generated DNGs.
I do not know if the DNGs created by Silverfast contain this checksum or not. If the DNG does not contain a checksum, LR/ACR will just indicate "not validated". The option here is to regenerate a DNG with any of the Adobe tools.
Oh, Lightroom=more better . Re-saving would force every file to be backed up again.
Yes, LR is the best option, but you need to have the licence. In relation to backup the files again, you can do it to a temporary folder and delete them after the process, so the only requirement is to have enough space on disk.
If starting with "non-verifiable" DNGs as explained previously, you may want to do this backup the first time, as it will not alter the raw image itself.
How do you do this from ACR Jeff?
I can't get that URL from Peter to open on my end.
The URL gives a warning because it it a https link with either an expired or unregistered digital certificate. In most browsers you can override this warning and get to the page. Since you don't have to input any information in the page, this should not be an issue.
