Underwater Colour Filter Sealife SportDiver SL40007 — red

Sealife SportDiver SL40007 — red is an underwater colour filter designed for compatible SportDiver lights and recreational underwater photography setups. The red filter compensates for the loss of warm tones that occurs as depth increases in blue-green water, helping to restore natural-looking reds and oranges in photos and video without relying solely on post-processing. It is a lightweight accessory intended to be attached to SportDiver light heads to improve on-site colour balance for divers and hobbyist photographers.

Advantages

The red filter reintroduces warm colour components absorbed by water, reducing dominant blue-green casts and producing more natural skin tones and marine colours at typical recreational diving depths. It is simple to attach to compatible SportDiver light housings and does not require additional electronic calibration or settings changes on cameras. Because it adjusts colours optically at the source, it can reduce the need for extensive colour correction in editing while preserving image detail.

Suitable for

• Recreational scuba and snorkel photography in blue-green coastal waters
• Underwater video capture at shallow to moderate depths where red tones are diminished
• Portrait-style underwater shots where natural skin tones are desired
• Quick in-field colour correction for hobbyist divers without advanced lighting setups

Key specifications

• Colour: red, designed to restore warm tones underwater
• Compatibility: for use with compatible SportDiver light heads
• Material: durable optical-grade filter material suitable for underwater use
• Form factor: lightweight, designed to be mounted on the light head
• Operating environment: intended for use in saltwater and freshwater recreational dive depths

How to use

Attach the red filter to the SportDiver light head according to the light manufacturer’s mounting method so the filter fully covers the light output. Use the filtered light while photographing or recording to introduce warm tones into the scene; adjust camera white balance settings as needed for the best result, although the filter reduces the need for strong white-balance shifts. Remove and rinse the filter with fresh water after use in saltwater and allow it to dry before storage.

Usage recommendations

For optimal results, use the red filter at recreational depths where blue and green wavelengths dominate (typically from a few metres down to moderate recreational limits). Combine the filter with proper exposure and close-range lighting to avoid backscatter and to maximise colour recovery. Regularly rinse and inspect the filter for scratches or fouling that could affect image quality.
