That is kind-of what I meant, the linear 16bit output from dcraw 
isn't handled very well by tools such as cinepaint or hugin.

The 16bit workflow that makes sense is to create gamma corrected 
output from dcraw and work with this in hugin/cinepaint exactly as 
you would with 8bit data.

All this is completely different to working with 'real' HDR 
floating-point high dynamic range data - Something I haven't managed 
yet.
