The first step is deciding how serious you are about taking underwater pictures. If you are a diver or spend hours in the water it may be worth investing in a underwater housing for a DSLR. The problem? A good case will cost as much or more than the camera. A bad case will destroy your camera. Obviously, a good case is necessary, however as an example, a case for the Nikon D300 runs around $1500.00. On top of that, the built in flash is unusable when the camera is in the case, so unless you are working in very shallow water, you will need to add a $500 – $1000.00 underwater strobe system. Again, this approach is only for those that are very serious about underwater photography. Although underwater housings are available for rent, before putting your DSLR & favorite lens into one you really want to know how well it has been treated in the past. Another possibility – although still expensive, DSLRs in waterproof housings complete with flash systems are sometimes available for rent in popular dive areas. Rather than taking a chance with your own camera in a rented housing, you might consider renting the entire package.
For the rest of us, the simplest and least expensive solution is to revert back to film. For $12.95 you can purchase a 27 shot camera loaded with Kodak Max film that is good to a depth of 50′. No flash, but an inexpensive solution for a one shot photo session. If you want flash, for $23.00 you can purchase a 35mm point & shoot camera good to a depth of 17′. The flash is not all that powerful – don’t expect to shoot more than a foot or two away from your subject.
If you are diving more than a few feet, flash or other camera mounted lighting is almost a requirement. Even in very clear water, just down to 30 feet or so results in less than 25% of the surface light. What’s more, the water does not filter out colors evenly. Your warm colors – reds, orange & yellows are the first to go – without camera mounted lighting everything shifts to blue.
For those that want more control over your camera, Nikon still makes an underwater 35mm camera, the Nikonos V. Although not inexpensive at $319.00, it can be used at depths up to 165′, and has adjustable shutter speeds, a variety of lenses & flash units and other accessories. The price is for the body – lenses are extra.
Film is certainly the least expensive way to go, however many of us have moved to the digital age & no longer keep paper prints, don’t want to file negatives or slides, etc. The solution may be a digital underwater camera. Although more expensive than the simple film point & shoot cameras, they can also be used as a general purpose camera out of the water. They have the advantage that they are an all weather camera; you don’t need to worry about using them in the rain, snow, or even shooting in the surf.
Like all digital cameras, there is a wide range of available devices. NexTag lists digital underwater cameras ranging from as little as $39.95 to $2500.00 or more. There are lots of choices.
