An underwater housing is what keeps your camera dry at depth. This is a critical job, since one drop of saltwater hitting the camera in the wrong place can destroy it. The prominent companies making housings generally have this problem well solved by design, else they wouldn’t be in business very long. However, being a dependable moisture barrier is not the only important quality to look for in housings. There are other key features and characteristics that, if absent, can really limit the capabilities and enjoyment of your underwater video system. We’ll look at all these areas to help you make a choice that’s right for you.
Frequently the difference between a great photo and a so-so photo is the background.
A great background can really make the photo stand out. The subject and background should work together with the other elements in the photo to really grab your attention or draw you into the work.
A lot of professional photographers spend as much time looking for a great background as they do looking for a great subject. It’s just that important in the photo. Figure 1 has a nice subject (Rock Beauty), but the background is poor. The background of this photo doesn’t help at all, in fact, it detracts from the photo.
A neutral or plain background can help draw attention to the subject even if the viewer doesn’t even realize that there is a background in the photo. Like figure 2, a Gray Reef Shark out in the Blue.
Patterns, such as the patterns in coral, sea fans, sponges, or schools of fish can create interesting backgrounds. Patterns can even be the whole photo. See figure 3 Juvenile Damselfish on Brain Coral.
Colorful backgrounds or subjects can help draw the viewer’s attention to the image. In figure 4 (Flamingo Tongue Snails on Sea Fan), the color of the Purple Sea Fan helps make the snails stand out.
So, the next time you get in the water with your camera, take a look at the backgrounds. See if that fish that you’d like to take a picture of, swims over or in front of a nice background. Does that Damselfish hang out over the coral or just hang out in the rubble? Look for backgrounds, patterns and color. You’ll be surprised at the difference it will make in the pictures you bring home.
What does an underwater video system cost?
Like anything else, the start up cost of getting into underwater video spans a range depending on the results and features you require. Basic underwater digital video systems w/o lights start around $900 new. At the far high end, a full featured prosumer-level HD system including HIDlights and an external monitor can run over $16,000. Keep Reading
