My post needs a bit of correcting...
sRGB is a gamma of 2.2. Windows is set up for 2.2 and mac for 1.8. It seems
more sensible to use a value of 2 for your work so you're not too far from
either.
(linux users can set this up with the rather nice gamma tool in Guidance.
there's a shot of it on http://dot.kde.org/1145962774/ )
