The Filter Kit includes a UV Filter, a Circular Polarizer Filter, and a FLD Fluorescent Filter for Daylight Film. Each filter in this kit can provide one of three enhancements to your imagery. Additionally, these filters are constructed from optical glass within an aluminum-alloy frame, which protect the front element of a lens from scratches, bumps, or impacts. The UV Filter is a general use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter. This UV filter is also useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur. The Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. 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 polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing 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. The FLD Fluorescent Filter for Daylight Film is a color correction filter that is designed to reduce green casts when shooting with daylight film under fluorescent lighting. It is constructed from optical glass for clarity and an aluminum-alloy filter ring is featured for durability while remaining lightweight.
