Hi Elaine,

I agree that some colors are shinier than others. Also, my brightness  
was not zero, but was the default of 1. I think however, I have  
tracked the issue down to the position of my lights. I had them pretty  
straight on and resetting this position gives the pov-ray shininess I  
was expecting.

Thank you,
