Stacking filters....

[Dominik Bauch]

Any reason to not stack a Schneider Linear Truepol polarizer and a 1/8 Hollywood black magic filter?
What order would be best? Assume that polarizer would be outermost filter?

Also what's the stop loss of the 1/8 Hollywood Black magic? Can't find that anywhere... True pol looks to be 1.3 or something, pretty high.

Thanks!

Linear Tru-Pol should be 1 and 2/3 stop loss. A lot of people just round to -2 stops. There's no stop loss with HBM filters. I stack them all the time. I'm not sure the order matters too much, my matte box has the 138mm Round tray at the rear, so the Pola goes closest to the lens by default. The stacking order makes a bigger difference with filters like Hot Mirrors.

Thanks, that explains why I couldn't find data on the HBM's...!
