Pre Dive Preparations
When you are lifting the O-ring, do not jam it up forcefully with the tool. Gently slip the tool alongside the O-ring and very gradually and slowly insert it beneath before levering up
Gently clean the o-ring but make sure not to pull the o-ring or misshape it.
Grease, Take a small amount of the special grease on your finger and apply it evenly to the O-ring. Too much grease itself can cause a leak. A thin even layer is ideal.
Test the case in a bath or sink. Firstly for only a couple of seconds pointing the camera down into the water lens first.
It is generally okay to insert up to two silica gel packages into the waterproof case as long as they don’t interfere with the camera’s operation. Be careful not to catch the package edges in the O-ring when you close the case.
Post Dive
Always rinse off the salt in fresh water after you are through diving. If salt water is left to crystallize on the case or O-ring, it will act like sand and cause leaks.
If there was potential for sand to get on the case, then be sure to hold the case with the buttons pointing down and vigorously swish it in the water when you soak it. It may be easiest to wash away the sand with a stream of water.
Re-Set The White Balance
Whereas there is no colour bias on land, light is diffused underwater so that the red spectrum appears darker. The deeper you get, the greater the diffusion effect, and hence, the greater the change in colours. Use the white balance feature to achieve natural coloration.
Built-in Flash and External Flash
The “marine snow phenomenon” is likely to occur when a built-in flash is used to shoot a subject at a standard portrait-shot distance. Use an external flash to avoid this problem.
Different Angle of View
When subjects on land and underwater are shot at the same distance with the same zoom setting, the underwater subject will appear larger in the image. This is a result of the angle of view being narrowed by refraction. Back up or expect a narrower angle underwater.
To avoid startling fish you are trying to photograph hold the camera at arms lenth.
To photograph big fish or schools of fish, a good technique is to slowly approach from below the fishes’ eye level and to avoid sudden movements. If you observe this cardinal rule, you can find yourself surrounded by dynamic, swirling schools of fish.
