(:=)))... well, digikam witch drive IPTC is not a sofware for you (:=)))...

You cannot compare negatif film and picture file. It's not the same :

metadata are data added outside the image data. When digiKam write/update IPTC 
for example, the image data (negatif film informations for you) are 
untouched !

The metadata are stored in other place in file, especially in a JPEG section, 
or in a PNG chunk, or in a TIFF tag. A lot of softwares, like photoshop for 
example, store metadata like this !

Also, if you don't want write IPTC metadata in picture files, well just 
disable the right option in setup.
