Underwater photography gel filter

The Lee Filters Scuba Blue gel sheet measures 24 by 21 inches and adds a rich blue hue to underwater images. It is designed for photographers and videographers who want to amplify natural blues without heavy post-processing. The large sheet covers a variety of lens sizes and lighting fixtures for creative flexibility.

Check light-source heat and mounting method

Verify that your studio or continuous lights do not exceed the filter's heat tolerance before attaching it. Ensure you have a frame, clips or tape that can hold a 24 by 21 inch sheet securely in front of the light source. Confirm the gel's colour effect matches the specific water conditions you shoot in.

Suits creatives needing strong blue tint

This sheet suits underwater specialists and studio artists who need a pronounced scuba blue cast for stylised work. It is not for buyers who want neutral colour correction or subtle warming filters. Photographers requiring small circular gels for lens-thread mounting should look at something else.
