Xrec Half-Frame Blue Filter for GoPro Hero5 Black - underwater color correction

The Xrec Half-Frame Blue Filter for GoPro Hero5 Black is an accessory designed to correct blue color cast when filming underwater or at the water surface. The filter mounts over the camera lens area of Hero5 Black housings and similar form-factor mounts to restore reds and warm tones that are absorbed by water at shallow depths. It is intended to improve natural-looking color balance in diving, snorkeling and other water-sport footage without digital correction in post-production.

Advantages

This half-frame blue filter provides targeted color correction for underwater use, returning warm tones and improving overall color fidelity in footage captured at shallow depths. Its form-factor is compatible with GoPro Hero5 Black housings and similar mounts, allowing simple attachment and removal. By reducing the need for extensive color grading, the filter helps save editing time while delivering more accurate colors straight from the camera.

Suitable for

• Diving and snorkeling at shallow to moderate depths
• Near-surface swims and surf sessions
• Water-sports footage where red and warm tones are desirable
• On-location shoots where minimal post-processing is preferred

Key specifications

• Type: half-frame blue corrective filter for action cameras
• Compatibility: designed for GoPro Hero5 Black housing and similar form-factor mounts
• Function: restores reds and warm tones lost underwater at shallow depths
• Mounting: attaches over the lens area of compatible housings
• Use environment: underwater and near-surface water filming

How to use

Attach the filter over the lens area of the GoPro Hero5 Black housing or compatible mount before entering the water. Frame your shot with the filter covering the portion of the lens as intended for half-frame correction; ensure the housing and filter are clean and free of sand or debris before mounting. When filming, monitor color balance on your display and adjust white balance or exposure settings on the camera as needed. Remove the filter after the shoot and rinse with fresh water to remove salt and particles, then dry before storage.

Usage recommendations

Best results are typically achieved at shallow depths where reds are partially absorbed—use this filter for snorkeling and dives up to the depth where natural red tones become fully lost. Rinse with fresh water after use and avoid abrasive cleaning to preserve optical quality.
