            Bug ID: 297771
          Severity: major
               URL: //home/ak/Dokumente/Zu_klaeren/120408DK.jpg

           Summary: WISH / ERROR: metadata in pics are not accessible in
                    batch queue manager (BQM)
    Classification: Unclassified
                OS: Linux
          Reporter: axel.krebs at t-online.de
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: Searches
           Product: digikam

User-Agent:       
Build Identifier: 

BACKGROUND:
I´m using new NIKON D3100 and new lenses 10-24 mm, 105 mm and 70-300 mm
First lens I intended to check in landscape picturing. Pictures seem to be
overexposed by one shutter number, at least. 
Rem.: This could be a problem of camera, the lens itself or of this very
combination.    

BUG EXPLORATION:
I tried to compare exposures from 105 mm with the ones made ba wide angles zoom
14-24 mm lens to unreveill the reason.

PROBLEM:
Unfortunately, when checking the "extendeed search" box, I found, that DK does
_NOT_ distinguish several photo- capturing modes the camera NIKON D3100 offers.

There is only a small number of pre-defined modes, as
- automatic, 
- without flash, 
- porträt
- landscape
- flowers (near shot)
- sports
- night-snapshot

These modes emphasize different settings; "landscape" tries to maximize
sharpness-range, sports uses short exposure times etc.  

Please compare
<http://support.nikonusa.com/app/answers/detail/a_id/16910/~/user's-manual---d3100---guide-to-digital-photography>
pages 28 ff.

Whereas DK extended search offers many fine grained search options, there is no
option to search for exposure types as described above.

As a consequence, one is not able to search all exposures made under a specific
modus like ´landscape´ ´children´ etc. Therefore, it is not possible to do
specific search for these items.

Most astonishing: when looking in "metadata" >> "EXIF / Producers remarks /
IPTC / XMP" all these information is stored in the pics, completely!!!

SUMMARY:
Please enable _ALL_ metadata available for search purposes!!!



Reproducible: Always

Steps to Reproduce:
1. just enable all metadata for usage in the search menu!
2.
3.
Actual Results:  
unsatisfying, as DK does not use existing information for further workflows.

Expected Results:  
DK should take advantage of all metadata available in any picture. 
At every plasce of DK, the prog should rely to the same data- independent of
the very location, an user gets into contact on these.
