Best Accessories to Trick Out Your CameraPhotograph: Scott GilbertsonOnce you have an action camera, you're good to go for most use cases. GoPro, Insta360, and DJI all provide helmet mounts and other ways to stick your camera where you want it. Both are great additions to your action camera kit. The GoPro ND filters handle all that for you. If you don't have a HEro 13, I've tested and like DJI's ND filter set for the Action 6 ($79).
