Available for many popular cameras of operators with specific accessory underwater housing. The simple and inexpensive models cost around 150 € and are suitable for diving to a depth of about 10 meters. Because of the many scuba divers, the training in a depth of 18 to 20 meter diving and should ensure that the simple underwater housings are suitable then only marginally. In addition to work in greater depth with a flash.
This is a better plastic bag sealed with a simple clip, the simple cabinet are made of high strength and flexible film. The principle is simple and works reliably until the water pressure pushes the body so that the camera controls are blocked.
For digital cameras with underwater housings that are manufactured for each specific model. For a higher quality of photographic equipment (SLR cameras with built-in electronic flash), there are more sophisticated underwater, but they are also much more expensive and costs depending on model 400-2000 €. This unit can theoretically diving depths between 50 and 80 meters can be achieved, but these products are no longer ordered in the normal photo shops, but usually needs through specialized mail order or at trade shows, or you can search in underwater webhosting.
Exemplary orientation for maximum depth of the dive housings with simple (on the commercially available products by Ewa-Marine in plastic wrap, can be applied to other restrictions on products from other manufacturers):
- Video package: max. 10 meters
- Small footprint: max. 10 meters
- Housing for Manual SLR: up to 15 meters
- Housing for AF SLR cameras: max. 20-50 meters (depending on model)
The underwater housing for exceeding the maximum depth are not necessarily fixed. Increasing pressure at depth, but the operation will be affected because the special film is pressed closer to the camera. For dives deeper than 15 meters should be rigid, prefer the pressure-sealed housing.
Underwater cameras with viewfinder complicate the picture, because there is only limited direct view through the viewfinder, because the mask. To correct the installation of a sports-finder or a high-eyepoint viewfinder that problem. Digital cameras with LCD screens easier in the underwater photography, allow the design of the next record and the place. Compared to analog recording technology increases depending on the size of the memory card, the number of possible shots. The digital data open the possibility of further processing. The same applies to digital camcorders, with their size flat screen as a viewfinder, the ever more high-quality photo features.
