This LEE85 Polarizer Filter from LEE Filters helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface while creating a warm cast over an entire image. This combined effect can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. Mounted within a durable and lightweight fiberglass frame, the LEE85 Polarizer Filter is designed to snap directly onto a LEE Filters LEE85 Filter Holder's installed guide blocks, allowing it to be used without occupying any of the filter slots created by the guide blocks.
The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizer filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, providing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizer filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.
For clarity and colour fidelity, the LEE85 Polarizer Filter is constructed from optical glass and includes a padded pouch for storage and transport.
