1 . 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.

2. Some cameras reset their flash to AUTO when the camera is

turned on. If you prefer another setting be sure to select it.

3. As soon as you enter the water, take a moment and check the

housing to see that it is properly sealed.

4. Next, check to see if there are any bubbles on the face of the

lens port. If there are, take your finger and remove them. If

there are bubbles on the lens port they can produce soft focus

spots in your photographs.

5. 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 2 feet (0.6m), you need to

use an external strobe such as the DS51 or DS1 25. With an

external strobe you can position it so nothing blocks the light

path between the strobe and the subject.

6. 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.

7. 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.

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. 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.

3. 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.

4. 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.

5. 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.
