[Gimp-user] boosting shadows



Hi -- I was working on a 16bit tiff trying to boost shadows in gimp similar to how I do it in raw photo development software.
I was almost able to do it, but not well, because gimp doesn't provide 
much resolution in the low end of the histogram when adjusting curves, etc.
The best solution I found in gimp was to use gmic and enlarge the curve 
dialog across two monitors, which almost gave enough resolution to 
adjust as needed, but it was still a pain, and the results weren't as nice.
I ended up using rawtherapee semi-successfully (the controls for the 
curves are easier to adjust) but none of the solutions compared to using 
the raw software I normally use (Canon's Digital Photo Professional) 
because it uses some kind of scaled histogram (e.g. log scale on x axis).
Any techniques anyone knows to get this done in gimp? I know there are 
other methods with masks and overlays and such -- I haven't been too 
impressed with them and am hoping for some kind of curve tool... maybe a 
plugin? Thanks!
