For years, we suggested that underwater video imaging was our recommended starting place for new divers. The time elapsed between exposing film underwater and the opportunity to review the developed film simply could not match the learning curve provided by the nearly instantaneous feedback offered by underwater video. The same instantaneous feedback is offered by underwater digital cameras and a computer. 

  Divers interested in underwater digital cameras should consider several factors before selecting their system: 

• Simplicity of Use
• Available System Accessories
• How You Will Use the Images

Simplicity of Use 

  As with underwater film systems, some digital camera systems are very simple; others are quite complex. One u/w digital camera has three basic settings while another camera has a 165 page manual describing (by my best guess) 65,000 different settings. Dealing with a complex camera system can be very frustrating. Basic camera systems make basic images. If basic images will fulfill your needs, why complicate your life? 

Available System Accessories 

  As the marketplace currently stands, a digital camera is placed into a waterproof housing in order to record images underwater. Some economy housings are not very durable and seem to be built with the same disposable product mentality that has been evidenced by video and digital camera manufacturers. Some full featured housings are equally as, if not more, costly as digital cameras. A variety of the lesser expensive housings offer what you see is what you get. There is no availability of an external flash…no accessories like wide angle or close up lenses. If your underwater images need to be improved by these features, you may be forced to start a new system altogether. 

How You Will Use Your Images 

  There has been a real debate over image size. Cameras tout 4 and 5 megapixel image size which is really important only if you are printing large sized images. If you are emailing images, putting them on web sites or simply storing them on CD’s, huge image files may not be in your best interest. Image files of 2 megapixels will make very acceptable 5 x 7 in prints. 

  Ultimately, a variety of factors come into play when deciding on a digital camera system. Cost, ease of set up for u/w use, available accessories, and image applications all will have an impact on your final decision.
