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.<br>

Thanks Adam,<br><br>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.<br>

Thanks for your help!<br><br>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.<br>
<br>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.<br><br>

</div>Maybe you want to vote for "digiKam could warn when writing metadata to<br>
pictures fails"?<br>

<br>
I think it is a significant problem if you chose "write metadata to<br>
pictures", but for some reason digiKam can only store the information<br>
in its database.<br>
<br>
I'm sorry for you if you lost a lot of tags.<br>

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