Actually both contrast and brighness are all the way up (could be why my
monitor is dying ;) and there's no bluring

Well it actually seems to be coming out in the wash since I forgot to
mention that the assumed_gamma value is 1.85 with a light source set at 
1.5
times the intensity of "white" light. even at 1.85 with a regular white
light source the scene is too dark.
