Hi everyone, thanks for the great response to my post.  Well, I've read
through all of them and I've come to the conclusion that there is NOT an
automatic way to do this in POV-Ray.  My goal was for my image to look
like an old B&W photo, old west style particularly.  I guess it seems to
me that the only real way to do it is to do what Ken said and just give
each object a grey color.  I haven't actually tried it yet so I don't
know how hard it will be.  Actually, I think it may give me some very
badly needed control over my colors and textures (I can never seem to
get them quite right).  I'll have a go at it and post my creation in
binaries.images when I'm done.  Well, here goes nothin'.  

Once again, thanks everyone for racking your brains trying to think of a
solution.  I really appreciate it.  

		Kyle
