onderwatercameras

Underwater cameras (Dutch: onderwatercamera's) are devices designed to capture images and video while submerged. They may be purpose-built units with sealed bodies rated for water immersion or standard cameras housed in waterproof enclosures. The design emphasizes water sealing, corrosion resistance, and reliable operation under varying lighting and pressure conditions, enabling photography in oceans, lakes, rivers, pools, and other submerged environments.

Categories include compact waterproof cameras that operate without external housings, action cameras with built-in waterproofing or accessory housings, and professional systems using mirrorless or DSLR bodies placed inside watertight housings with external strobes and macro lenses. Photographers may also use conventional cameras in purpose-built housings to achieve higher image quality or more flexible rig setups.

Key features vary by type but commonly include depth ratings, rugged construction, manual and automatic white balance settings, macro and wide-angle capabilities, and compatibility with lighting equipment such as strobes and video lights. Many models incorporate underwater scene modes or color-correction options to counter the loss of red light with depth.

Applications range from recreational diving and snorkeling to underwater videography, macro photography of marine life, wreck exploration, and scientific fieldwork. When choosing a model, users consider water resistance, image quality, battery life, weight and buoyancy, available lenses or macro options, and the compatibility of lighting and housings with their planned activities.

Maintenance emphasizes cleaning and drying seals after use, inspecting O-rings, rinsing with fresh water to remove salt and sand, and periodic servicing. Proper buoyancy control and careful handling are important to reduce equipment damage and ensure safe underwater use.
