Your best colors and effects will be where the sun still penetrates the water: Dive or snorkel

at a vertical sun from 10 am to 2 pm in a depth not greater than 25 ft. / 8 m.

Each depth and light condition has its own attraction. Experiment and capture different

effects at different depths and scenes. In crystal clear tropical waters you will get great

turquoise water colors to a depth of 20 ft. / 7 m, then an intense blue, and a wonderful deep

blue beyond 40 ft. / 12 m. In the SeaLife ReefMaster RC film camera the built-in “Coral

Flash” will intensify red and yellow colors of close objects (4 ft. to 6 ft. / 1.2 m to 1.8 m) and

leave the blue background untouched. Color corrected macro lenses will intensify the warm

colors (red and yellow) even more and moderate the flash.

Look for rich color contrasts. You may use the Sealife External Flash to add color and bright-

ness. To really illuminate coral or any area further than 5 ft., you cannot just increase the

power of your flash, but you must position one or two external flashes sideways of your lens

and direct it at an angle of 20 to 30 degrees at the object. If the water is not as clear as you

may wish, choose closer objects. Use 1 flash for high contrast, and two for even illumination

and rich colors. The MACRO 3X Close-Up lens can be used for distances of 2 ft. to 4 ft. /

60 cm to 1.2 m, the MACRO 8X lens for 14” to 16”/35cm to 40cm.

Just a black silhouette against the bright water surface can make a dramatic shot.

A “halo” effect can be created by the sun or a light source behind a person or a sea creature.

In bright conditions on land or in snorkeling use ISO 100 print film or ISO 64 for slides. A sec-

ondary strobe can be used to reduce “marine snow”, caused by the flash hitting microscopi-

cally small particles like algae or plankton. The primary flash of the camera must be covered

with a flash reflector which reflects the light towards the external flash sensor and not directly

towards the target. SeaLife Macro Lenses also help to reduce marine snow.
