A glass polarizing filter mounted on a cassette used in GoPro Hero4 and 3+ cameras. Simple and quick installation - push-in. Reduces flash, improves color saturation, sharpens images especially when shooting over water and in the snow. Note: using the BacPac LCD or Battery BacPac, Gopro joins (as of April 2014) an entire H3 size cartridge, not 3+, so this filter may not work with such a cartridge!
The filter is mainly intended for field shooting. We use the house when, for example, we photograph objects on a glass table.
Sunny day : the filter will eliminate the excess light, reduce glare, remove the exposed elements.
Partially cloudy : the filter will deepen the blue, increase the sky / clouds contrast, improve the color saturation and reduce glare.
Cloudy : The filter can eliminate glare on metallic surfaces. Limited applicability, but also the filter will not spoil movies.
Full cloud cover, dark : filter will not help anything - film without a filter.
When you want a very good quality of the shot, make sure that the filter does not mist up - it can fog like any optical element. If it has evaporated, wipe it with a soft cloth.
