Bug 299922

I use digital cameras sind some 7 years: Canon Powershot A 710 IS, Canon Powershot A 720 IS, Fujifilm FinePix S2500HD Review, NIKON D60, NIKON D3100, receiving several other formt from friends.
Many presumably older file formats do not support all modern features of metadata storage, e.g.

"Old" Canon raw format "CRW/CR" accept tags when adding them, but do not stores these infomation reliably; when checking these pics later, the tags are missing. Work is lost, time has been spent useless...

From similar observations, I concude, the support of several file-formats might be different.

On the other side, it would be easy to maintain a simple collection of supported file formats and to match this listing with the very version of digikam. 

If doing so, it would be a small step to exclude certain file formats from specific manipulations. Why wasting time for unrealizable steps. 

In extending this idea, ohne should uses this capbility even when opening pics, already. 

Reproducible: Always

Steps to Reproduce:
1. unfortunately, digikam forces the user to waste his time without beeing sure of succcess
2. 
3. 
Actual Results:  
please see above

Expected Results:  
as describe above, digikam should offer a pic-format depending manipulating engine. 

for my opinion, this is more than a wish for new feature- it deals with workflow, time saving and professionality
