Hi jdd,

I ight be wrong, but as much as I understund digikam (super app!) it is 
designed to work with the complete picture. If you want to apply corrections 
only to parts you also want to have soft selections, layers and a lot more... 
Use Gimp for these tasks.

But it is very easy and fast to crop the images in digikam and even keep the 
aspect ratio. Just remove the unwanted parts and do the corrections then...

If you don't want to crop every single image of a series of scans (and scanned 
them all in the same position) you can also use imagemagick within a script 
to crop all together and overwright them or save them to another file name. 
See: http://www.imagemagick.org/Usage/

For more complex corrections you can use layers and masks in Gimp, even with 
grayscales, gradients etc. to acchieve about any effect you' desire...

good luck!

Daniel
