I have a particular project for which I need to render a scene in black 
and white. Ideally, I need a filter (like a photographic filter) which 
shows a scene in black and white when we look through it. 

So imagine a rendered scene which is in full color, except a part of it 
which is scene through a special glass filter which is held up.

I looked at the archives and the nearest solution I can find is to use 
hf_gray_16 in the global settings, and re-import that to somehow 
generate a black and white scene:

Is there any other method I can use to do this in a single render?
