Two renders of the same scene, the top with gamma correction and the bottom
without. The rightmost pixels of each sphere are only 5% apart (244 vs.
232) but gamma correction makes the top light source seem much brighter.
For the discussion with similar subject in p.g. at
http://news.povray.org/povray.general/thread/%3Cweb.439a1b692d1f46002a1c213f0%40news.povray.org%3E/
I'm not making a point about which is right or wrong, just doing a little
excercise.
global_settings { assumed_gamma 1 } // or not...
sphere {0 1
texture {
finish {ambient 0 diffuse 1}
pigment {rgb 1}
}
}
light_source { <100, 0, 0> rgb 1}
camera {location -3*z look_at 0}
