Something Id love to have built into the physical camera is polarizing lens filters. Theyre common in car photography for knocking back facing reflections, and its something Id love to be able to work with without having to control the fresnel of all my shaders in a scene.

Sounds like a pretty good method...the only issue for me is most of our work is for high res still that go through photoshop, and we try to avoid rebuilding the image using all the elements as photoshop is terrible in 32bit. Generally we try to supply the retouchers with beauties, as a photographer would, and a key part of our workflow is also getting early stage lighting sign offs that we dont have time to use IDs and passes, but have to look quite polished, so I'd need something that I can save out of the framebuffer.

What you might be able to do is use the reflection element in subtract mode to remove it's contribution and then use the raw reflection using the reflection filter as a mask to add it back over in linear dodge - might work if you don't have anything too burnt out?

You could have a look at this shader:

It has a polarisation option. Downside is you'll have to change you material setup though.
