K&F Concept offers a range of filters for GoPro action cameras, including the new Hero 13 Black.Filters used with GoPro cameras provide several benefits, such as enhancing footage quality and versatility.The ND filters control the amount of light entering the lens, while the CPL filter reduces glare from reflective surfaces. FPV drone pilots can enhance video quality by balancing exposure, smoothing motion, and creating cinematic effects using ND filters.The ultra-light aluminum filters are made to maintain the camera's water resistance, are not stackable and do not have a mark.Using ND or CPL filters with GoPro works best in manual mode with a tripod for stability and sharper results.The ND1000 will probably stay mostly in your photo bag as it reduces light by ten stops.The recommended settings for FPV drone cinematic shots are: resolution and frame rate, shutter speed, ISO, white balance, and color profile.The combo pack of these filters consisting of two kits including three cleaning clothes can be ordered directly from Kentfaith or their Amazon store.They have another GoPro 9-13 filter kit for $52.99 that contains ND8/PL, ND16/PL, ND32/PL, and ND64/PL.
