The Backscatter Flip Filters 55mm Polarizer Filter is used for above water video to bring in better colours in high sunlight areas. The Flip Polarizer is an optical filter that passes light of a specific polarisation and blocks waves of other polarisations. This filter works much in the same way that polarised sunglasses do and can bring in richer colours and better images.
While Backscatter initially designed the Flip Filters System for underwater use, they quickly realised that there was a benefit to introducing polarisers and graduated ND filters. In addition to these types of filters, they have also had excellent results using the +10 Close-Up Lens and the +15 MACROMATE Mini on land.
Use with the Backscatter Flip Filters 55 mm Threaded Adaptor Filter Holder which will allow you to mount any filter to the FLIP7, FLIP6, FLIP5, FLIP4 and FLIP3.1 frame or TOP FLIP. Works on the GoPro Hero 3, 3+, 4, 5, 6 and 7 action cameras.
