Setting metadata for a few images (like 500) freezes digikam.

[Anders Lund]

Hi list,
In preparation for my next event, I am experimenting with digikam. One
of my thoughts is to get a description or title into every image, which
may be a default.

So I tried doing this:
- Go to an album with about 500 photos.
- Select all.
- Put something in the description field of the metadata sidebar.
- Press Apply.

Now, digikam is mostly frozen, having worked for > 10 minutes. Most of
the files in the album are raws, but I checked the experimental option
to write to raw files.

Is this how the state of this is? Because I mostly find this unusable,
if this is the way it works, I need another tool to do this task :(
Tricks to make this work better?

Kindly,
Anders

Don't use this option. I plan to remove this. The RAW write support in
Exiv2 still unstable and nothing work on it.

The option is disabled by default. Don't change it.

Hello,

Please take a look at this bug report.
https://bugs.kde.org/show_bug.cgi?id=382002

I recorded a video of what is happening on my machine and shared it there.

Is the same happening to you?

Please post comments in the bug tracker.

I'll uncheck it again, and maybe it was a bit silly to test with that
many inmages.

The reason is that I use an external program (darktable) for processing,
and it would be smart if meta data could be shared. For my planned
workflow, in some cases the description would be used for adding a text
to the image using darktables built-in facility for that. I'll find a
workaround for now :)

This option from Exiv2 is not finalized. The Exiv2 treads to support
this feature sound like the option is too dangerous. RAW must still
read only. There is a risk to corrup RAW files. I recommend to not
touch this option.

digikam and darktable share xmp sidecars pretty good (I have not noticed any bugs).

Also I think the slow process of adding descriptions to images isn't related to adding metadata to RAW.

I have experienced same behavior with JPEGs.

Maybe my machine is slower than what an average user have nowadays... (Core i5-2520M 2.50GHz with 8Gb RAM

Or maybe my HDD is slow or something else... (2.5" 7200 RPM over SATA 3.0 Gb/s bus)

So I could elect to add the data to the xmp file? But for my planned
workflow, I rely on them being in the image, I read (and write) them
with perl Image::ExifTool.

All my RAWs (CR2s) appearently survived the experiment. I'm quite sure
the slowness comes from digikam unnessecarily reloading and rewriting
thumbnails.

If you write to sidecards you can review the metadata using a simple text file viewer/editor like notepad on Windows.

darktable writes to sidecards too (if the option selected in settings)

And yeah, I agree on your thought that the slowness comes from digikam unnessecarily reloading and rewriting
thumbnails

My planned workflow goes about like this:

- Take a lot of photos
- Select some for publishing
- Add a default title to all of those (although it would be smart to
  just add that to ALL photos, as I may later publish extra)
- Add a special title ("bow #") for photos containing boats with
  bow numbers
- run a script (digikam batch processing) that generates a title for
  those images, using a database, this will be something like "DEN 1442
  Peter Jensen", script is written in perl. The title is written back
  into the photos.
- Process and export images using darktable (I usually us a style, and
  then adjusts rotation and optionally exposure and others).
- run a script (digikam batch processing) that generates a footer
  image with some logos and text (including the title) that is then
  glued to the bottom of the jpg using ImageMagick.
- publish photos to facebook and web gallery using digikam plugins.

So I need something that can safely read/write on the xmp files, if I
use those. Appearently Image::ExifTool can *write* xmps, but not read
them.

Kindly,
Anders
