Lindsey Optics Brilliant-Pol Polarizing filters are designed for specifically for cinematography and are available in all of the standard professional filter sizes. They are extremely efficient at reducing reflections on glass and water. They also can saturate blue sky and increase color saturation in landscapes by reducing micro-reflections in the scene.
With Brilliant-Pol polarizers you have more choice about how much reflection to remove, in order to tell your story better.
The Brilliant-Pol product range includes Linear Polarizers and Circular Polarizers in 5 professional sizes: 4.5" Round, 138mm Round, 4"x4", 4"x5.65" and 6.6" x 6.6".
As with all Lindsey Optics filters, the Brilliant-Pol Polarizers have a rock-hard 7 layer anti-reflection coating which reduces stray light, improving contrast and color saturation.
The ultra light wooden camera mattebox takes 4.5 inch round filters. It is a great design and the matte box is great but 4.5 inch round is not very common. Seeing the Lindsey Optics option I knew it would be great and it was a little cheaper. The quality of what I received was wonderful. This polarizes hard. On monitors I am able to go from full brightness to completely blocking them out. A nice option for shooting interviews in rooms with screens.
