The i1 Series filters from Snake River Prototyping are professional filters for the DJI Inspire 1 camera and the DJI Osmo. The i1 Series filters are a professional combination Neutral Density and circular polarizer filter for the DJI Inspire 1 camera, as well as the DJI Osmo. The protective UV filter that comes standard on the Inspire 1 is screwed off and this filter is screwed on in it's place. This neutral density filter reduces rolling shutter artifacts (e.g. jello) by slowing the shutter speed of the Inspire 1 camera while the circular polarizing qualities of the filter cut glare and increase the contrast between clouds and the sky.
