Freewell Insta360 GO Ultra Standard Day - 4Pack

ND stands for Neutral Density. These filters reduce the amount of light entering the camera without altering the color balance, allowing for longer shutter speeds or wider apertures in bright conditions.

The choice depends on the brightness of the scene and your desired effect. ND8 is for moderate brightness, ND32 for brighter conditions, and ND64 for very bright sunlight. Experiment to find the best balance for your shot.

A CPL (Circular Polarizer) filter reduces glare and reflections from non-metallic surfaces like water, glass, and foliage. It also enhances color saturation and contrast, making it ideal for landscape and outdoor shooting.

These filters are designed to be used individually. Stacking filters is generally not recommended as it can degrade image quality and cause vignetting.

While the filters themselves are made of durable materials, they are not designed to be submerged. Protect them from excessive moisture and clean them promptly if they get wet.

Use a soft, lint-free microfiber cloth. For tougher spots, a dedicated lens cleaning solution can be applied sparingly to the cloth, not directly to the filter.

The Standard Day pack offers a balanced range of ND filters (ND8, ND32, ND64) and a CPL for general daylight. The Bright Day pack typically includes stronger ND filters for extremely bright conditions.

Ensure you are attempting to attach the filter to the correct camera model (Insta360 GO Ultra) and that no debris is obstructing the connection point.

Verify the filter is clean and free of smudges. Ensure it was properly seated onto the camera lens without any gaps.

Confirm that the CPL filter is being used and that it is oriented correctly. Adjusting the camera's white balance may also help.

Gently re-seat the filter, ensuring it is flush against the camera lens. Check for any damage to the filter or camera mount that might prevent a tight seal.
