The Tiffen Series 9 Low Light Polarizing Glass Filter was developed for shooting indoors in low-light conditions and for situations that do not provide enough light for a standard polarizer to be used. The low-light polarizer reduces glare and reflections and adds just enough punch to saturate colors and maintain decent contrast without compromising image quality.
Note:
If you would prefer a Low Light Polarizer with a warm touch, order BH# TIWLLP67. This filter will have a Tiffen 812 warming filter incorporated into it
It gives the camera professional that little touch of polarization that is needed to keep the scene crisp, especially if the low light polarizer is being used indoors with one or two other filters
The low-light polarizer is purposely designed with a one-stop compensation factor
