This Formatt-Hitech Circular Polarizer Filter Kit contains 5 replacement filters for use with the Formatt-Hitech GoPro Hero 3 filter holder. These filters help to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions.
Each filter measures 33 x 36mm, is 1mm-thick, and is constructed from CR-39 resin.
Prior to use, remove laminate from both sides of filter
The filters' design has three rounded edges and one straight edge; when the filter is placed in the holder, the straight edge should be in the top left corner as it appears facing the user in order to ensure a proper polarizing effect
Due to the delicacy of the material of this filter, a clear protector filter is recommended for use in front of the polarizer to protect it from scratches
Note: Filter Holder Is not Included
