[Digikam-users] lost all tags on canon raw images

[Jim Dory]

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
