I gave is a quick try out the other day, after the FSV thread.
Couldn't get it to do anything other than turn my perfectly acceptably exposed raw files(NEF) into pure white, approximately +5Ev over exposed mush.
Added as much -ve Ev compensation only to reveal cloudy purple mush rendered over a white background!



Have no idea what's going on.
Tried on D800E, D300 D5500 and D70s files.

Worked ok on jpgs tho.
