The screenshots too bright eh? Gamma at 3.0... That's because I find the maps too dark. So I ram up the gamma for the screenshots, if not nobody can see anything (you've said it, but that's the reason). Maybe I'll tone it down to 2.5 or 2.0 in the future then. =)
And oh, I noticed the screenshots here seemed to be much brighter than what the pictures were in my computer.
