lost all tags on canon raw images

[Jim Dory-2]

I'm devastated, though I'm probably to blame for not understanding what I was doing. I spent many evenings over the last few months tagging my photos in Digikam. I've used digikam for quite some time - back in the .9 series anyway - and through many problems it always kept the tags to my images - though back then they were maybe all jpegs rather than raw. Just lately however all my raw image tags disappeared - including in the list of tags in the tagging sidebar that I had created in the last few months.

I am using Gentoo linux and probably was running Digikam in pretty much default settings - I don't believe I had the option checked (that I've since found) to write tags to IPTC.

My problem seemed to appear when I upgraded my kernel from a 2.6.31 to a .32 version. Apparently, at least in Gentoo, there is a bug with Gentoo's version of those kernels that breaks connection with NFS shares. When I first booted to the new kernel, I had apparently had Dig. running in my last KDE 4.4 session so it fired itself back up and couldn't see the NFS share where most images live. I figured no problem as I had had similar problems in the past and didn't lose tags. I even used to keep the database on the NFS shares before I learned that was a mistake and moved it to my home directory last year. That solved other problems. So I fixed the NFS/Kernel problem and repointed Dig. at the images. It is possible when I pointed it at the images I pointed at a more parent directory than before to include a few other directories with images that before I had added piecemeal. But when the database had finally scanned in images again, all tags except the jpeg images had been lost.

I assume they are lost for good but am posting this just in case there is something I'm missing.

I don't have a good understanding yet of IPTC or XMP and need to read through the manual on how D. works with them. I have VirtualBox running a WinXP with photoshop and Adobe Bridge, and have added keywords to an image or two in the IPTC metadata of Bridge - but when I open up D. I don't see them in the metadata. (The IPTC and XMP sidebar windows, when I view them, are just big blank areas - I suppose this must have something to do with needing a template? - this is an area I need to read up on).

I've checked the first 5 or 6 settings in Settings/Common metadata actions, and have tried adding tags to an image, but nothing shows up in the sidebar/IPTC.

I pretty much would rather tag images in D. as Bridge so far seems more clunky in doing that, but need to know that tags/keywords will make it into the image metadata and hopefully be readable by other programs now and in the future. Hopefully this is possible.

thanks for looking, Jim

I can't help you trying to find the lost tags, but I suspect you will be told they're gone (I hope not), and that you should have kept a backup of the database.  I learned the hard way about the latter too, but only lost a few hours work, so not that much of a problem.

I notice that Lightroom is configured to request a backup once a week by default, and all you have to do is tell it where you want it to be stored.  I wonder if digiKam should do this too, rather than requiring you to work out which files to copy yourself.

Thanks for that Peter,

When you say backup the database, I assume you're referring to the digikam4.db file. Ok. However, back when I was keeping the database on the NFS shares there were many times I had to delete it and let it rebuild so I could again view the images. The jpeg tags were always back - I just don't know if my raw image tags were also there or perhaps I hadn't tagged them yet. So I guess I had a false sense of security - thinking the tags were somewhere in the image rather than database.

I've noticed when I go to the menu Image/Metadata/Edit IPTC (or XMP) on a raw image that the dialog window is broken. I cannot navigate around in it or mouse clicks have no effect. Works fine on jpg images. So something on Raw is broken - perhaps something on my computer. I run Gentoo's cutting edge (their unstable branch) so am probably asking for trouble.

thx, Jim

Maybe you want to vote for "digiKam could warn when writing metadata to
pictures fails"?
https://bugs.kde.org/show_bug.cgi?id=220204

I think it is a significant problem if you chose "write metadata to
pictures", but for some reason digiKam can only store the information
in its database.

I'm sorry for you if you lost a lot of tags.

In any case I recommend making backups from time to time. I use rsync
with snapshots, but not with cron (yet). Similar to this solution:

Thanks for your help!

It seems that on my computer at least, raw metadata in Digikam is broken. I will avoid tagging until I get that figured out - I'll see if I can work it out in another program for tags/keywords in the meantime.

Does raw tags/keywords work for others in Digikam? Can people use the Image/Metadata/Edit IPTC for instance? On mine, I cannot navigate or click on anything in that window on a raw image whereas jpegs are fine.

I think, it is a problem with Canon Raw, or at least I know it does not work with Canon. It is the plugin that Digikam used to write the metat data, not really a digikam issue.

I setup a backup that runs every 4 hours just copies the database to other folders. I almost lost all mine when I did an upgrade recently, but the backups saved me. Good luck

Thanks Adam,

Do you use Canon Raw? I'm curious of what strategy I should use for these images. If tagging these raw images don't write to metadata but only the database (currently the issue on my computer at least), then are you or whomever that is doing this with Canon raw just tagging and relying on the database - thus hoping that the issue is someday fixed? Or don't care? In a perfect world for me, I could tag my raw images, then when one moves me to edit it and save as tiff or jpeg to share on something like flickr - which I do now - that the keywords/tags would move along the stream and show up as tags on flickr or other photosharing site. But mainly it seems if the tags were written to metadata keywords then they would be transportable to other programs far into the future without worrying too much about losing the tags/keywords.

cheers, Jim

Thanks for your help!

It seems that on my computer at least, raw metadata in Digikam is broken. I will avoid tagging until I get that figured out - I'll see if I can work it out in another program for tags/keywords in the meantime.

Does raw tags/keywords work for others in Digikam? Can people use the Image/Metadata/Edit IPTC for instance? On mine, I cannot navigate or click on anything in that window on a raw image whereas jpegs are fine.

Maybe you want to vote for "digiKam could warn when writing metadata to
pictures fails"?
https://bugs.kde.org/show_bug.cgi?id=220204

I think it is a significant problem if you chose "write metadata to
pictures", but for some reason digiKam can only store the information
in its database.

I'm sorry for you if you lost a lot of tags.

In any case I recommend making backups from time to time. I use rsync
with snapshots, but not with cron (yet). Similar to this solution:

Well, I just looked at DNG and it seems to work okay writing tags to metadata. I used the DNG converter under tools to convert a cr2 file. It shaved the image down from 7.5 MB to 6.9MB. Not significant for my Canon 30d but maybe if I upgrade to the much larger image size of say the 7D, then it may start getting important. I did a brief google on the subject and I didn't find that it has any deleterious effects so far - maybe some more research is in order. Had you considered doing that and if so, why did you reject it? It is one more (or a couple) steps in post processing which isn't great.

Thanks Adam,

Do you use Canon Raw? I'm curious of what strategy I should use for these images. If tagging these raw images don't write to metadata but only the database (currently the issue on my computer at least), then are you or whomever that is doing this with Canon raw just tagging and relying on the database - thus hoping that the issue is someday fixed? Or don't care? In a perfect world for me, I could tag my raw images, then when one moves me to edit it and save as tiff or jpeg to share on something like flickr - which I do now - that the keywords/tags would move along the stream and show up as tags on flickr or other photosharing site. But mainly it seems if the tags were written to metadata keywords then they would be transportable to other programs far into the future without worrying too much about losing the tags/keywords.

cheers, Jim

I tried converting a .cr2 file to .dng. I then imported both files into
ufraw. The results were not the same. This shows that the data is being
processed in some manner. As the point of shooting in raw is to have
unprocessed data available I will not use .dng.

Me too, when it has to do with raw (from Olympus E-3 and Panasonic LX-3)

Thanks for that Andrew,
 

I'll have to look a bit more closely. DNG is raw. The image I tested on did initially look different but then I noticed the tint and temperature (using Bridge) sliders were at different points. So I made them match and the image looked exactly the same (comparing CR2 and DNG). So am curious about your results.

dng is one form of raw, but there is no common meaning of raw amongst
camera manufacturers, which is one of the reasons for creating dng, to
try and improve interoperability. I don't know what is done when
converting from Canon cr2 to dng and my test was very simple. It seems
that it may have been too simple and maybe I should try it again.
However I am not happy that by default the sliders need adjusting to get
the same results. It'll be a while before I get to this though.

Andrew
