|The pol camera filters I've tried haven't given as complete an extinction
|as other material, but they are flat, and that helps; and as you note, they
|rotate in their cell, allowing you to adjust them to any projector.
|However, their effectiveness will be greatly reduced unless the projector
|uses equally high quality polars, and it would be worthwhile to equip your
|projector with these as well.
|They will be handy for other uses, when shooting film in a glary light, you
|can check the orientation of the glare.  If you fish, you might find that
|sunlight off the water isn't always horizontally polairized.  And think of
|the money you'd save on those 'Mad Scientist' Halloween costumes.
