with it before attempting to read it underwater. Also practice composing
and focusing the camera by eye, before using it underwater to get the feel
for this operation as well.

Changing Exposure Settings
o
Using the camera in its Manual (M) Exposure Mode gives you the ability
to change either shutter speeds or apertures to control the exposure the
way you want. Get used to making these changes while your eye is in the
viewfinder and you are referencing the LCD display for guiding you in
the exposure process. The Command Dial is set to change shutter speeds
or apertures. Practice operating each of these controls so they become
instinctive in operation.

Familiarize yourself with the movements required
o
Utilizing each housing control to properly and efficiently change camera
settings. Some controls only require a straight pushing movement, while
others may require pushing and rotating simultaneously to operate.

Using the camera's light meter to determine ambient light
o
There are three light meters in the D40/D40x/D60: Matrix, Center
Weighted, and Spot. Read the D40/D40x/D60 instruction manual for
complete descriptions on each of these meters and when to use each. No
matter which one you choose, they all help guide you to the proper shutter
speed and aperture combination for proper ambient light exposure. Where
you aim the meter is also important. In underwater photography, it is
important to remember to aim the meter at the background water or "sky"
to get the proper exposure information. It is often necessary to gather this
information, make your exposure settings, and then re-compose the scene
before shooting.

Sometimes it is good to operate the AE-L button
o
When locking in the exposure value of the background before re-
composing and taking the photo.

The ISO Sensitivity setting on the camera
o
This is the same as the film speed that photographers set on film cameras,
with one small difference: there is no film. This setting is the equivalent
of the film speed you would normally set. The higher the ISO sensitivity
number, the more light is captured and the brighter the image. Higher ISO
sensitivity numbers have more
"Noise" , a term that is the digital
equivalent of grain in higher speed films. Try starting out with a lower
ISO sensitivity such as ISO 200 if the lighting conditions permit.

Get close to your subject when shooting underwater
o
This will improve the effectiveness of your strobe in restoring lost color.
It will also expand the sharpness of the image by reducing the amount of
backscatter between the lens and the subject.
