Maybe our Cousin can add a simple demo what srgb input results in what rgb being
used?
#version 3.8;
global_settings{ assumed_gamma 1.0 }
#for (i,0,1,0.1)
#declare c = srgb i;
#debug concat(str(i,0,2)," : ",vstr(3,c,", ",0,2), "\n")
#end
maybe add splines to it to show the relationship.
or the relation with gamma in photography how exposure time and development time
influence gamma while having the same min and max density as a result. And how
you can play with photographic paper to compensate for gamma errors a bit or use
it for artistic expression, kind of changing assumed_gamma .... sorry, got
carried a way, thoughts of red lights and darkrooms
