My bad, I had "gamma" on the from brain talking about the display gamma... I
meant "ambient 0" (which is what I've put in there in response to "If you
are using ambient, try turning it down or off")
I'll play with that gamma image and see if I can get it right. Attempts I've
had with "gamma.gif" in the past to determine precisely the display_gamma of
my machine (as described in the help file) haven't seemed to work.
Currently I've got display_gamma as 2.2 (the default I believe and
recommended for PCs) and assumed_gamma 1.0 for the image.

Ah, I see the problem.
Help file section 6.11.2 says : "The default is a white ambient light source
set at rgb <1,1,1>"
I had assumed that it was rgb 0 if unspecified, which is apparently not the
case. It doesn't help that I seem to keep my moniter rather dark too so it
didn't show up that badly for me.

Ah ha! ;-)
Well I just can't use that assumed_gamma 1.0, I'd have to do some extreme
contrasting of textures to use it. So I will only leave it out or use 2.2,
like Display_Gamma is set.

Setting assumed_gamma to 2.2 was what
I did to keep the look of my older pics. Just
remember to use 1 when you begin a new scene!
