Original Note:
Three filter polarisation is an extremely well known function that is very simple for even the most layman to understand. two 90 deg orientated polarisers block 100% of photos. Insterting a 45 degree in the middle allows 50% through it and 25% the back filter. https://faculty.csbsju.edu/frioux/polarize/POLAR-sup.pdf
