I stand corrected.

Downloading (while having my 3rd mug of tea)

Will report back :)

Doesn't seem to make much of a difference, does it?

Looks like I need more help from you folks to figure out where exactly
the problem is rooted.

I second that ;)

Was the optics_mod.pov or optics_mod_2.pov provided above of any help?

Sure.. The original scene is destroyed.

My hope is/was the simplified version might give you an idea, you find a 
solution, which - by lucky chance - solves all photon/media related 
problems.

Unfortunately not. I need you to toy around more to give me that one
breakthrough idea.

It's really frustrating that there is not the slightest glitch to be
seen with the Windows version.

3 different pics by changing 1 line of the original optics.pov...

Does this raise any interest or additional frustrations?

Yes... The pics are brighter. I used assumed_gamma .5.

No, actually not. I know that there /is/ a bug lurking below the
surface, and unless I know exactly what causes it, I cannot rule out
that it may also strike at Windows users under /some/ circumstances.

I dunno... care to tell me /what/ you changed? ;)

> Yes... The pics are brighter. I used assumed_gamma .5.

Why on earth would you do that?
(Then again, I did ask you to experiment, so...)

What really intrigues me, and what I would like to ask you to try and
investigate, is why only /some/ of the light rays are affected; why
don't /all/ the blue and /all/ the red rays end up blazingly white?

There must be /some/ reason for this, and I reckon that it might lead to
a useful clue.

This is what gave the 3 different results:

#declare MirrorTex1 =
texture {
     pigment {color White}
     //finish {ambient 0 diffuse 0 reflection  1/1}
     //finish {ambient 0 diffuse 0 reflection 1/10}
     finish {ambient 0 diffuse 0 reflection 1/20}
}

Original reflection - Image ...01...
10% - Image ...10...
5 % - Image ...20...

Keeping my fingers crossed!

Maybe my CRT-Monitor is too dark. That why I did it ;)
