(...) Could be an effect of the 'ambient' value for the transparent colors. If you look at the pov file I sent you, you can see that I have used the following for color47: #declare Color47 = #if (version >= 3.1) material { #end texture { pigment { (...) (13 years ago, 5-Jun-11, to lugnet.cad.ray)

(...) If I understand it correctly, 'ambient' is what you see if all lights are off. I usually turn this down very low (zero). 'Diffuse' is reflected light from other surfaces, you'd want quite a lot of that. (...) Yes, I think the default (...) (13 years ago, 2-Jun-11, to lugnet.cad.ray)

(...) Actually, the sum of *all* your lights should not be too much over <1,1,1> as some parts of the image may be saturated. I usually use 0.5-0.7 for the *brightest* light, and 0.1-0.3 for filler lights. Remember it's easy to modify light (...) (13 years ago, 2-Jun-11, to lugnet.cad.ray)

(...) I'm 99++% certain that's not the case, given the input data Jeroen was able to recover for me. I think removing reflections would be a lot of work, better to change the properties of the surface to get them not to happen. (13 years ago, 2-Jun-11, to lugnet.cad.ray)

It looks to me like each model / row of models was rendered in POV-Ray individually and then PhotoShopped together. Probably removed any reflections when combined on to one image. Scott (13 years ago, 2-Jun-11, to lugnet.cad.ray)
