Distance Without Close-Up Lens:

The distance of film cameras to the object should never be less than 4 ft. / 1.2 m, ide-

ally 5 ft. to 6 ft. / 1.5 to 1.80 m. Digital cameras can be taken as close as 2 ft / 60 cm.

Longer distances are only successful in extremely clear water and to background objects.

The general rule is: Water visibility (hori-

zontally) should be 10 times the shoot-

ing 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 judg-

ment.

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.

Film: 4 ft./ 1.2 m

Digital: 2 ft./60 cm
