I don't see anything like that, just large pixels when I enlarge it.
Jpeg artifacts are not too bad either.
I'm using OE5.5 viewing inline, but saved pic is still OK viewed in
PSP or Irfanview.

Hey you guys make me crazy. I was already in fear to be color blind
but sorry, there are defenetely no color artefacts. If you see something
in the original image you really should adjust your crappy monitor because
its red, green and blue cathod ray tubes are no longer in focus (some
monitors have a little screw on the back side to adjust this convergence
error).
And if you blow up the thing by using a resampling filter, those color
shifts are typical artefacts produced by crappy software.
Attached is the blown up version WITHOUT resampling filter, so where
are your blue pixels?

Hi, it's really me hidind behind that alias. This was a lighting test
but I also wanted to see how photographers and CG hobbyists see it. On a
photography BBS the earlier version got comments like: nice, looks fine,
needs more contrast and sharpness etc. I applied those and other
suggestions to this version.
The scene is just one mesh and 4 4x4 area lights. No radiosity. The
texture is an image map which is also used as bump map with curves
adjustment. Looks boring when rendered directly (30 minutes). Ater 30
minutes in Gimp + Photoshop it looks much nicer. It's a variation of the
rendering by layers method with 2-pass film transfer curve fake.
Professional compositing software probably has this kind of functionality
built-in.
I guess the result is close enough to photorealistic if you have to
dig up a microscope to look for the "cheats" :)

I see red on the left, green/blue on the right exactly as with PP8 and
ACDsee

same here. And I'm VERY sure my monitor is perfectly all right. I have
changes settings all the way around, different color "temperatures" and what
else my CTX "Ultra Screen" holy monitor (hahahahah) supports. I have *never*
had any color issues on this electron cannon...... And if something is
wrong, I should have other issues too. And the color shifts are left-right
oriented and scale with the image, so it's defenatly in the pixel colors....
let me tell you some rgb values: the left (reddish) has #ad786a (or cmyk
30%, 55%, 55% and 7%) and the right (greenish) part has #6f9878 (or cmyk
60%, 25%, 61% and 4%).
Hey, Graphicus, what's going on here? Did you render something with POV-Ray
and postprocessed it some way just to freak us out? :P
Just three ways to get to this picture: no POV-Ray involved whatsoever,
POV-Ray rendering with postprocessing, pure POV-Ray material. If it's the
third one, could you please tell us how you did that color shifting!?
Regards,
Apache

Hey man! This image rocks! You had me going here hahahahahah I'm a bit of a
POV purist/freak but the result is absolutely stunning and believe me it is
photorealistic that's why I was very suspicious.... :)
And now how/where dit you get that mesh?

Congratulations! Any image that looks real enough to fool so many of _us_,
is amazing. I looked at it long and hard, and simply couldn't find anything
in it that made it look "rendered" rather than photographed.
Amazing!

Those "cheats" made me believe it was more like a photograph than a POV-Ray
thing hehheheheh.
