Re: When to "convert metadata to xmp"?

Thanks to Hert who added some more helpful info in the Mantis ticket: https://mantis.idimager.com/view.php?id=3274 I'm still interested to know if anyone thinks my settings look dangerous (as per my question of this thread), but I guess whatever happens I have to figure out what to do to reduce the ...

Re: When to "convert metadata to xmp"?

I forgot to say: The files converted from raw to DNG have the exif data shown also in the xmp. But after such a file is processed by ACR, some information is no longer in the xmp but it seems it's still in the exif. So, presumably ACR reads in the exif info from either exif or xmp, but re-writes the...

When to "convert metadata to xmp"?

I posted an issue to Mantis today. I use Photoshop CS5 (because it's the last version with a perpetual licence) and it includes Adobe Camera Raw 6.7 ("ACR6.7"). That hasn't been updated for about 5 years, so it doesn't support new cameras. So, as suggested by Adobe, I convert raw files to DNG using ...

Disable Sizing if you want to copy original file. Some of the sharing option will then not be available.
Hert, I'm curious about this. Why does "sizing" need to be selected as a pre-requisite for accessing the "Metadata" options?

Re: Integrity of JPG and DNG files: Any suggestions for managing bitrot?

Unfortunately (for us Windows users) Chronosync seems to be for MacOS only. Incidentally, one thing that makes file mirroring harder for me is that all my drives (other than the system drive) are encrypted by Veracrypt, for which VSS (Windows's Volume Shadow-copy Service) apparently does not run. As...

Re: Integrity of JPG and DNG files: Any suggestions for managing bitrot?

Thanks, I will take a look at BeyondCompare and ExactFile to see how they work. Also I still need to make time to look at SyncBack again (since I already have it) so that I can see whether there's a way to maintain a hash database of originals and/or backups.

Re: Integrity of JPG and DNG files: Any suggestions for managing bitrot?

It would be useful to understand why they were missed. Is it possible that these three files had been added to the catalog after your last verification of the folder? Unfortunately I don't see any comfort there. These folders were originally ingested to IDImager and converted to DNG on 14 Feb 2012,...

Re: QUESTION: what is your nr1 reason to use Photo Supreme

Versioning, to associate the final display version of each image with the original from camera or elsewhere. Without versioning I would go back to my old folder based system which did everything else that I need quite adequately. (Honestly for me the labelling is net/net a huge waste of time, but I ...

Re: Integrity of JPG and DNG files: Any suggestions for managing bitrot?

Well, it turns out that the file verification under Photo Supreme's "Verify Folders" process may be incomplete. I had a look in Windows Explorer at the affected folder where Photo Supreme had found 145 files "changed" which on closer inspection turned out to be corrupted. In Windows Explorer: Window...

Re: Integrity of JPG and DNG files: Any suggestions for managing bitrot?

Thanks for those thoughts. I had forgotten that "verify folders" does integrity checks on the files themselves, and this appears to be what I am looking for. I ran "verify" on the main branch of the photo folder tree last night (several hours) and it found "147" changed files, of which 145 turn out ...

Re: Integrity of JPG and DNG files: Any suggestions for managing bitrot?

BTW I read that DNG has a file hash embedded, but the only ways to check it (that I could find) are with Lightroom (which I don't use) or by opening every file individually with Adobe Camera Raw.

Integrity of JPG and DNG files: Any suggestions for managing bitrot?

I had a file system corruption last night (*), and had to restore about 6000 files from backup. Afterwards, I started thinking more about image file integrity. I think I don't know for sure that all the other image files on the main drive escaped damage. Equally, I don't know for sure that there is ...

Script Error: Access Violation when importing with DNG handler enabled

If I run the "import to catalog" process with the DNG handler enabled, it always crashes with "Script Error: Access Violation". This happens whether or not there are any raw files in the set of images to import. To proceed, I have to click "OK" on this dialog once for every file I was trying to impo...

Re: Can't remove W: drive from the catalog

Unfortunately that does not seem to be the case (or at least, not obviously).
The drive shows as <<offline icon (red folder)>> W:\ [35E0-05F1] and then the number of images is shown as 0. If I click on the zero then nothing appears in the viewer pane.
