Gamma.
This is the typical effect of gamma correction, which POV-Ray 3.6 didn't
do properly (with the result that scenes were designed "wrong" to /look/
"right"), but which POV-Ray 3.7 now does a pretty good job at (with the
result that scenes designed "wrong" now indeed /look/ "wrong".)
Now the first thing to note here is that theoretically, POV-Ray 3.7
/should/ do gamma correction in the same "wrong" way as 3.6 when
"#version 3.6" is used. What you observe is that this doesn't seem to be
the case, so we /may/ still have an issue there, and I'll have a closer
look at this.
I might need a bit of information for this purpose:
- What is the Display_Gamma setting you use (if any)?
- What is the File_Gamma setting (if any)?
- Are you using "assumed_gamma" in the scene? If so, what is it set to?
- Are you using image-based textures in the scene?
You might need to have a look at the master POVRAY.INI for this purpose.
Note that POV-Ray 3.6 and 3.7 have separate master POVRAY.INIs.
