Thanks, I am quite pleased how it turned out.

I refined how I make df3's as well. I use the slice method taking three 
passes. One for each colour channel. But there has always been a colour 
imbalance with the red channel being the weakest.
After the discussion last week and understanding it a bit better. I 
found a way around.
My photo editor (PSP 9) has an adjustment called "Channel Mixer". There 
you can take one colour channel from the image and mix it across all of 
the channels*. Mitigating PovRay's method of turning a vector into a 
scalar value. I think I might be able to cut out two of the three 
initial passes using that adjustment in batch mode. :)

I thought I would share before I forget.


* This method can also be yours. Send only one dollar and a S.A.E. to 
the following address... ;)
