Hi.

If, for the rendering of a scene, I use:

global_settings { assumed_gamma 1 }
Display_Gamma=1

and assuming that the scene is dim enough so there will be no clipping.

If I make the scene twice as bright, by doubling the value of all lights and
ambient values, can I expect that the resulting rendered scene will have all
the pixel values doubled?
