Managing raw and jpeg at the same time?

Hi,

what is the best current practise for that problem?

    * I'd like to keep my raw images as the master and enter Tags,
      Annotations, things for IPTC and XMP for the master file (i.e.
      into the database since writing to raw images is not supported and
      I'd like to keep my raws untouched)

    * In those cases where I am happy with the raw image, I'd like to
      export them to jpeg or png automatically (batch) into a directory
      outside the digikam repository, to avoid having the same image
      twice in the database, but with the given data in IPTC and XMP

    * In those cases where I am not happy with the raw, I'd like to use
      ufraw and write a ufraw file with the corrections and parameters
      I'd like to use. This means that there is not a second picture
      file, just something that generates a second picture when called
      with ufraw-batch. Again, should export and keep IPTC and XMP, but
      that time should appear as a separate image with a separate
      thumbnail in digikam.


Any way to achieve that?


best regards
Hadmut

That is a way I currently don't go. I am not realy satisified with the
results of digikams raw converter in most cases. If  I don't like the
jpeg results I use ufraw and generate a new one. All my files are under
control of digikam. The ufraw results usually are located in an other
local directory, but under digikam as well. If I have already tagged my
files (jpeg and raw) I usually export the exif/iptc/xmp data, copy them
to the new directory and add them to the new created files (after all
needed work on the picture). If I am satisfied with the result I copy
the resulting jpegs back to the original directory (and overwrite my old
jpegs). As I am doing regular backup every night there is not much loose
of data (and I have the raws untouched anyway).

I don't know any automatic way of this. There is much handwork in the
pictures anyway, so the little copy actions is done without increasing
the time that much. I currently use some scripts to handle some of my
most used parts automatically. Currently I don't know digikams
batch-system very well - I don't know if this is possible with it as well.

In digiKam, one can select target image, go to Image / Metadata / Import
Exif and select the source image in the file listing dialog. Then do the
same for XMP or IPTC... Target metadata are overwritten. Good for one
image, but not for an every day work.

My target is simple "copy all metadata" and "paste metadata", preferably
via keyboard short-cut. I do not know how to do achieve this in digikam,
hence I plan to do so via Nautilus scripts.
