[Tig] ND filters for projections

Hi All,

I wanted to ask the tig a question about ND filters to bring down projector
brightness in situations where all the mechanical and electronic methods of
reducing light output weren't cutting it.

Do any of you have any insights on what brand/types of NDs work best? The
ones I've tested seem to exhibit some troubling uniformity issues.

I'm looking for a 1/3-2/3 of a stop reduction. So a .1 or .2.

Any advice would be appreciated.
