autotagged images ?

[Julien T]

Hello digikam users,

In my current workflow, I try manually to tagged picture that can/plan
to be used for panoramic or HDR.
I would want to know if there is a way (currently or maybe a planned
feature) to autotagged pictures depending on some characterics ?

For example
- When detecting "would-be HDR" (High Dynamic Range / Pictures merging
candidates): if I have 3 pictures at almost the same time (1-n sec),
same meta, but (normally) just a light level difference
(ExposureCompensation meta), add tags 'autotagged' 'hdr'
- When detecting "would-be panoramic merge" (later to batch with
hugin): If I have a sequence of picture with a time difference less
than n sec (usually 1-2), same other meta, add tags 'autotagged'
'pano'. A could-be problem is when I'm doing pano and also taking 2-3
shots w bracketing/different ExposureCompensation. Usually sequence is
between 3 to 10 images (x3 if bracketing).

Thanks.
Cheers,

Julien

Nothing like this is implemented yet, but i remember few entries in
KDE bugizilla, into Tags section about this subject. Take a look and
comment.

Here what I found

* Bug 158437 - Add ability to create/assign a tags to pictures while importing.
https://bugs.kde.org/show_bug.cgi?id=158437
* Bug 279544 - Tag image for unsharp pictures
https://bugs.kde.org/show_bug.cgi?id=279544
* Bug 128333 - digikam automatic photographic tags
https://bugs.kde.org/show_bug.cgi?id=128333
* Bug 157308 - Automatically tag edited images in digikam
https://bugs.kde.org/show_bug.cgi?id=157308

What I see are two needed things:
* search pictures based on complex conditions (group of meta / actions
/ calculus or external program results). For me, in this kind of case,
a free unique search field (a la google) with boolean and parenthesis
would be more efficient than gui for each field. Also one of the
could-be problem is be able to make selection base on image meta and
"nearby" images (be it near in time, near in sharpness or whatever)
* 'autotagged' them either after some actions (like import, export or
edit), either on demand

Bug 128333 seems the more "fit all" of them.
