Good to hear it. I always wondered and thought you were a purist. :)
Now I know why. I may have been a little bit over ambitious picking that
scene to start off with.
I'm still having problems with the red/cyan images that I don't have
with yours.
Ah! well. It's called learning. :)

Two good examples of the limitations of red/cyan.
High contrast; very dark beside very bright, without a transition.
---I use mostly gray scale images to limit this.
Saturated colour channels; Full red on the red side and full cyan on the
cyan side(this means the use of black).
---did I mention gray scale images already ;-)
The picture is fine, the use of red/cyan anaglyph is poor.
Shutter glasses all the way for this scene.

-I might reduce the camera separation by half.
-When joining the two pictures, place the picture frame at the viewing
plane(zero separation)
-Make sure the scene camera only has horizontal offset.
For almost all of my scenes when I go to make the right/left image, I
place the scene in a union and the camera at 0x lookat 0x. I them move
the union(scene) around to give the correct depth queues, and only
change the x offsets on the camera to make my right/left images.

I like not this news. :(
But I think you have saved me a lot of time. :)
I shall ponder.

Limitations in the scene itself?

That's what I was aiming for.

This one I got right. :)

I will try that, thanks. I generally move the camera.

Nor had I, TBH. Incidentally, is it really 13 rears since I wrote that?

¦¦¦ A typo? Or have you been born again?
BTW Bravery is what other people do. We just get on with it.™

A thought about that ghosting: maybe that is due to a slight colour
discrepancy between the red of the image and the red of the spectacles?

I think Stephen's on the right track and there are some images which are
not suitable for anaglyphs.
