If you render LDView’s POV output using the POV-Ray 3.7 beta release, you will
see that the colors all look washed out. This seems to be due to a difference
in the way that POV-Ray 3.7 handles gamma correction. There are two things that
you need to do to fix this:
- Add Display_Gamma=1 to your command line options (there’s a box in the toolbar in the Windows version for setting command line options). This should fix the colors in the preview window, but not the output file.
- Create an include file that contains the following line and set that include file as the top include in LDView’s POV export settings:
global_settings { assumed_gamma 2.2 }

Note that you can just manually paste that into the top of your file, but that
gets old pretty fast. Also, if you already have a top include, just add the
above line to it.
I’m not sure what the long-term solution to this problem is. POV-Ray 3.7 gives
a warning that it doesn’t support the assumed_gamma setting, and yet the
setting still has the desired effect.
Thanks go to John Winning for info on the assumed_gamma setting.
