  I mean that I shave off everyday, but not fully. :)

What about the white hair club, Thomas?

And let's not forget the no hair club.

Well we could go the extra mile and put a fingertip near the edge :)

The houses? It's rubbish :( It's actually a test scene for a 
neighborhood of houses setup I was working on the other day. I idea was 
to test cells and place the appropriate unit block according to the 
surrounding cells. It works, but adding complexity seems to multiply 
certain problems like roof shingles not meeting up right.

My webcam takes aberrated shots similar to this. I had originally 
designed the code so that I could add fake elements to scenes and tie 
them into real photos. I can still do that, but I doubt I would be able 
to fool any of you :)

stbenge, I tried your aberrate scene today and I can get the film grain to work
but not the chromatic abberation.  I've tried using both the default settings
and some random ones on my own.  Any advice as to what I might be missing would
be greatly appreciated.  I really want to try abberatting some pictures because
it will contribute a lot to my undetailed amateur images. =)  Thank you for the
work you put into this!  If it matters, I'm using POV 3.6.1 on a windows
machine.

Hello,

I tried it with 3.6 and it didn't work for me either. So I came up with 
this workaround. Replace the last object with this:

sphere{<0,0,10>,12
  pigment{
   #if(Noise>0)
    crackle solid
    scale .001
    color_map{
     [0 rgb 0 transmit 1-Noise]
     [1/6 rgb y transmit 1-Noise]
     [2/6 rgb 0 transmit 1-Noise]
     [3/6 rgb x transmit 1-Noise]
     [4/6 rgb 0 transmit 1-Noise]
     [5/6 rgb z transmit 1-Noise]
    }
    #else
    rgbt 1
   #end
  }
  interior{
   ior 1.0
   dispersion Aberration
   dispersion_samples Aberration_Samples
  }
}

I went ahead and uploaded a complete 3.6 version to p.t.scene-files.

Hi,

Thank you very much!  Your work around makes the chromatic abberation work as
shown in your previous pics.

I went through your code and just a few minutes ago saw that it was the effects
plane that was causing the problems.  As a temporary fix I just changed the
plane to box{2,-2 ....[the rest of the code in the plane block]...} .  It seems
to work too, but because you understand your macro more in depth than I do at
the moment I shall use the code posted by you.  Thanks again.
