g) Distance Without Close-Up Lens
The distance of film cameras to the object should never be less than 4 ft. / 1.2 m.,
ideally 5 ft. to 6 ft. / 1.5 to 1.80 m . Longer distances are only successful in extremely
clear water and to background objects. The general rule is: Water visibility
(horizontally) should be 10 times the
shooting distance.
The built-in flash is designed for
foreground illumination and richer colors
at distances up to 5 ft. / 1.20 m. The
orange “Coral Flash” of the ReefMaster
RC will help to avoid the U/W blue effect
of near-by objects. Always wait until the
green FLASH READY light on the back of
the camera turns on before taking a
picture (about 10 sec).
Tip: Measure your closest distance “Chin
to Fin” on land. Once you have determined a length of 5 ft. / 1.5 m., stretch out your legs
under water and test your distance judgment.
You will soon learn that distances underwater appear 1/3 closer than they actually are.
The ideal distance is 5 ft./1.20m… “from chin to fin” without macro or wide angle lens.
Minimum distance without close-up lens.
