Julien is right... Even Ansel Adams suggested to darken the borders of 
the prints to "don't let the eyes wandering outside of the photo". I 
love this technique because make the shot look less "flat", and a lot of 
people usually make the borders slightly darker (many times you won't 
even notice it, you need to see the original to see the change).

Really, it would be great if we could do a feather selection of part of 
the image and let some tools act *only* on it or only on the remaining 
part of the image (just as an inverted selection). For example, for 
darkening borders I could select the central part of the image, invert 
the selection, and use the curves tool to get the desired effect.

This way we could do a lot more things, without the need to add more 
tools. In this moment I don't see any use for the selection tool in 
digiKam, but maybe I didn't look carefully enough...


Do you think I should add these wishes to the bug-tracker? Sorry if it's 
not a new idea...
