Waterproof Digital Cameras Vary In Depth Perception
Underwater photography has always intrigued many people, especially those with an interest in aquatic life. The need for waterproof digital cameras expands beyond the professionals and educational users as more amateurs are trying their hands at snapping pictures of coral reefs and colorful fish. Although its use does not end there as some amateur photographers are expanding their picture taking experience to include their swimming pools as well as the beds of local lakes.
When looking for waterproof digital cameras you will have to know at what depth the majority of the pictures will be taken. You will also have to understand the difference between water resistant and water proof. Placing your expensive digital camera inside a plastic or rubber housing does not turn it into a waterproof digital camera and the extra humidity alone could cause serious damage.
With water resistance, the camera is generally going to survive if the user is caught in a rainstorm. These cameras also usually carry the notation of being rust resistant as it would take a heavy, driving wind or rain to allow dust and water to get into the inner workings. However, waterproof digital cameras are designed to withstand submersion to certain depths of water.
Camera's Seals Dependent On Water Weight
As water becomes deeper, the amount of weight it applies to any object becomes greater. Waterproof digital cameras are sealed to protect the insides of the camera against water to a certain water weight. Even though the camera may be listed as being waterproof, there will be another number explaining how deep the camera can go before it is subject to water damage. The average, low-end waterproof digital cameras are typically safe for about five to seven feet. Taking the camera into deeper water increases the chance that water is going to seep through the seals and damage the camera.
Many professional underwater waterproof digital cameras are designed to withstand much more pressure and when oceanographers are shooting under several hundred feet of water they often use a special housing to take some of the pressure off the seals of their cameras. Those buying cameras specifically for underwater use will expect to pay more for their equipment and the deeper it is protected, the more they can expect to pay.
In additional to the waterproofing seals, underground cameras will also have to adjust to using a lower level of available light. Using a flash underwater is not conducive to getting a good picture and most waterproof digital cameras have a bright, steady light available to provide adequate illumination.
