Empty field

[olivier mimet]

Thank you very much.

Ok, 3 entries of your list seems related with my concern.

In order to secure my tests and arguments before posting, how can I get 
the field(s) name linked to the drop-down list shown in the advanced 
search tool for item "Photograph informations/Camera/The make of the 
camera" (see attached screenshot) ?


NB : this question because the EXIF field "Make" embedded in my sample 
is "NIKON CORPORATION" while "NIKON" is displayed....

Thanks in advance.

Best regards

Olivier
