Mounting a ring light can vary depending on the specific model of light you have, but there are several common mounting options that you can consider.
Light stand: Many ring lights come with a mounting bracket that allows you to attach the light to a light stand. Simply attach the bracket to the bottom of the light, then attach the light to the stand using the provided screw.
Tripod: Some ring lights come with a tripod that can be used to support the light. Simply attach the light to the tripod using the provided screw or mounting plate.
Camera mount: If you're using a smaller ring light, you may be able to mount it directly to your camera using a camera mount. These mounts typically attach to the hot shoe on top of your camera and allow you to attach the light to the mount.
Clamp: In some cases, you may be able to attach the ring light to a surface using a clamp. Simply attach the clamp to the surface, then attach the light to the clamp using the provided screw or mounting plate.
