 Due to the power required to operate the camera flash and
LCD screen it is a good idea to start each dive with a fresh set of
batteries

t
urned on If you prefer another setting be sure to select it
 As soon as you enter the water take a moment and check the

If you are shooting with the camera’s builtin flash and the
cameras lens is set to the widest angle you may need to zoom
the lens slightly or a shadow may appear in the lower left
corner of closeup photographs The lens port may block some
of the light Installing the flash diffuser will help to eliminate
the shadow
(You can test this above water)
To shoot photographs closer than  feet (m) you need to
use an external strobe such as the DS or DS With an
external strobe you can position it so nothing blocks the light
path between the strobe and the subject

 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  feet (m)will not have much
color
 The camera’s builtin flash is very close to the camera lens The
flash can light up any suspended particles in the water and they
can be recorded in your picture This effect is called backscatter
To eliminate as much backscatter as possible photograph close
Photograph in clear water; do not stir up the sand or silty
bottom If backscatter becomes a problem in the environment
you are photographing an external flash will help eliminate
much of the backscatter
 Digital cameras have a slight lag time between when you press
the shutter release button and the camera actually takes the
picture Hold the camera steady a second or two after pressing
the shutter release button
 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
 Underwater flash is used to restore the warmer colors filtered
out by the water as well as to illuminate the subject When
photographing underwater set the camera to use flash on
every shot If the camera’s flash is set to AUTO and the sun is
behind your subject the camera may see enough light that it
does not fire the flash With the sun behind the subject the
subject is shaded (dark) and needs flash for a good exposure

 When using daylight or flash if your camera consistently over
or underexposes the image you may want to adjust your
camera’s exposure compensation settings Many cameras allow
you to adjust both available light and flash exposure with an EV
control in the camera’s menu
 Many photographers transfer their images to the computer
where they can fine tune the appearance of the image Many of
the image manipulation programs make you think you can
magically correct any image taken and make a good picture
One thing to remember when using image manipulation
programs if the image is overexposed much of the color is
missing If the color is missing you cannot adjust it If images
are slightly underexposed the color is there it is just dark and
you can adjust it to some degree So if you error in exposure it
is better to have the image slightly underexposed than over
exposed
