- Compatible with: DJI Osmo Pocket - MCUV filter Reduces haze and improves contrast in video and digital images by minimizing ultraviolet UV light. Especially useful in high altitude, snowy, or beach environments, it helps eliminate the undesirable blue cast. Provides a high level of transmittance. - CPL filter Removes reflections from non-metallic surfaces such as water or glass and glare from the sun. Increases color saturation, producing deep, rich scenic images. Also helps reduce the amount of light entering the lens. - ND filter Reduces the amount of light entering the sensor, giving you the ability to create your own shots by allowing more control of the camera's aperture, exposure time, and sensor sensitivity (ISO) settings. The numbers on the back indicate the dimming level. - Use scenarios 1) Bright outdoor landscapes, such as mountains in snow or beach scenes, where you want to minimize haze and maintain vivid colors without overexposure (MCUV and ND can be used together as needed). 2) Shooting on water or through glass, where reflections and glare are a distraction and color richness matters (CPL filter). 3) When you need tighter control over exposure and motion, such as smooth footage or creative depth of field, by adjusting aperture and shutter with the ND filter (ND filter).
