Photo Tips

1.The number one rule in underwater photography is eliminate as much water between camera and subject as possible. Get as close as you can to the subject, then use the zoom. If you are using flash, subjects beyond 6 feet (1.8m)will not have much color.

2.Digital cameras have a slight lag time between when you press the shutter release button and the camera actually takes the picture. It only takes a slight amount of pressure to trip the shutter, if the shutter doesn't trip immediately don't push down harder on the shutter control as you may damage the camera. Hold the camera steady a second or two after pressing the shutter release button.

3.Do not shoot down on subjects as they will quite often blend into the background and be difficult to see in the photograph. Shoot subjects straight on or shoot up at a slight angle using the blue water as a contrasting background.

4.Underwater flash is used to restore the warmer colors filtered out by the water as well as to illuminate the subject.

5.For balanced lighting meter the background and set the camera aperture accordingly. Use TTL, adjust the strobe's power settings, or move the strobe closer or farther away to properly expose the subject with the chosen camera aperture.
