When using POV-Ray 3.61 the following all produce the same image(as far as I can
tell).
For any file with assumed_gamma 2.2 in the global settings.
#if (version < 3.7)
#version 3.5;
global_settings { assumed_gamma 2.2 }
#end
and, in the command line.
-w768 -h576 +a0.3 Output_File_Type=t
or
-w768 -h576 +a0.3 Output_File_Type=s
or
-w768 -h576 +a0.3 Output_File_Type=n
With POV-Ray 3.7b the gamma correction has changed to the command line only.
To get the same picture as in 3.61, I need to use:
-w768 -h576 +a0.3 Display_Gamma=1 File_Gamma=1 Output_File_Type=xx
Without 'File_Gamma=1' the picture looks the same in Winpov render window, but
the resulting image looks different(than 3.61) in an image editor.
Is this the correct way to update scene files for 3.7b?
