[Gimp-user] galen rowell filter?

[Rei Shinozuka]

is there a (relatively) simple way to add a "galen rowell" filter.  
that's the late national geographic photographer to made great use 
out of graduated color filters to bring out the colors in sunset, 
etc. 

these sky colors are often become washed out due to overexposure 
necessary to expose the darked earth-based objects.	

thanks,

-rei
