Open your povray.ini, which will be in your povray folder, in any text
editor then add at the end:
Display_Gamma=2.2

For example an extract from mine:
  Library_Path=C:\DOS\POVRAY
  Library_Path=C:\DOS\POVRAY\include
  Library_Path=C:\DOS\POVRAY\include\mine
  Display=on
  Display_Gamma=2.1
  +dgt

For most PC monitors gamma 2.2ish should be OK, but I don't know about
LCDs or Macs. Anyone else with a different monitor gamma, but using
"your" pov source should then see what you see.
Check "3.2.2.2   Display Output Options" in the docs.

Hope this helps

Alf

Couldn't see my post when I checked so sent it again to be sure.
Around midnight UTC I find povray.org a bit slow here :-(

I think posterization only affects the number of levels of color in the 
image. This would be more of a conversion to a completely different 
pixel layout, as well as a resolution change. (Hmm, I wonder what a 
computer screen with a Fibonacci layout would look like...and how would 
the pixels be addressed?)

I've put 3 images on my website that will give you an idea what
single-colour spheres will look like. All around 47k.

duck1.jpg and BlueFoot.jpg - from photos using spheres, and
RedBird.png using squares this time for a neighbour to use as a sewing
pattern.
