Underwater camera housing

Underwater camera housings are waterproof enclosures that protect cameras in aquatic environments, crucial for fine art and scientific underwater photography.

About this subject

An underwater camera housing is a waterproof enclosure that allows photographers to operate cameras at depth. Typically made from anodized aluminum or high-impact polycarbonate, it uses rubber O-rings to seal out water. Pressure resistance varies, with professional models rated to 100 meters or more. The market offers housings for compact, mirrorless, and DSLR cameras, featuring external controls for focus, zoom, aperture, and shutter.

The importance of this equipment extends beyond hobby: scientific expeditions, National Geographic documentaries, and films like "Oceans" rely on housings to capture the underwater world. The history dates to the 1950s, when Nikon launched the Calypso, the first underwater camera designed by Jacques Cousteau. Since then, innovations such as housing connections for external strobes and dome ports for refraction correction have improved image quality.

Interestingly, pressure increases by one atmosphere every 10 meters of depth. Housings are tested in hyperbaric chambers before sale. Notable brands include Ikelite, Nauticam, Aquatica, and Subal. In the 2020s, the rise of mirrorless cameras spurred development of lighter, more compact housings without sacrificing durability. Brazil, with its 7,000 kilometers of coastline and areas like Fernando de Noronha and Abrolhos, has an active community of underwater photographers using these enclosures to document marine biodiversity and promote conservation.

Frequently Asked Questions

What is the maximum depth an underwater housing can withstand?

It depends on the model and material. Professional aluminum housings can handle 100 meters or more. Polycarbonate recreational housings typically support 40 to 60 meters. Always check the manufacturer's rating.

How should I maintain the seals of a housing?

After each use, clean the O-rings with a lint-free dry cloth. Apply silicone grease formulated for O-rings. Replace O-rings periodically as they wear. Always perform a leak test before diving.

Is there a difference between housings for still cameras and video cameras?

Yes. Video housings are often larger to accommodate external monitors, HDMI connectors, and power cables. They may also include handles and mounts for microphones and lights.
