Using the BetaFPV ND16 Filter for your Naked Camera is a breeze. Just plug it onto the lens of your camera, and you're good to go. This filter is designed to fit perfectly with the Case V2 of the Naked Camera. When you're filming, it'll give you better - looking footage and reduce the Jello effect. It works great in different lighting conditions, especially when there's a big contrast between bright and dark areas. As for maintenance, use a soft, clean cloth to gently wipe the filter if it gets dirty. Avoid using harsh chemicals or abrasive materials as they might damage the filter. Store it in a safe place when not in use to prevent scratches. That's all there is to it! Enjoy high - quality filming with your BetaFPV ND16 Filter.
