This paper deals mostly with HDR, but there are some interesting aspects of intra-camera light transport issues for the non-HDR shooter.

Interesting concept using a scrim of sorts like this. It's difficult to see how this apparatus could be translated into any type of practical device / software for general use, what do you think?
One other question that it brings up, is how much 'glare' in practice arises from atmospheric or water (in our case underwater) diffraction and dispersion issues vs in camera glare. This technique would not discriminate between the two. Just finished reading High Dynamic Range Digital Photography by Ferrell McCollough, an easy basic read.

Interesting! It appears to be very effective, although only for still-life scenes because the mask must be moved to record the entire scene.

Agreed. Not practical in any real sense for dynamic photography but the concept made me wonder if doubling up on polarizing filters (crossing axis) might give some GFS control (port to lens scattering?) when shooting sun balls. I know this method has been used in scientific/astronomy photography. Perhaps just a mental exersise.
I plowed through Christian Bloch's "The HDRI Handbook" a while back. Quite a grind but informative on many levels beyond HDR.

It seems that half the process described is software related, so it would appear that just using a filter(s) alone may just degrade the image.
I posted a thread on polarising filters here a while back
