Capturing memories is one of the main
reasons why the camera was actually invented.
And man has worked towards capturing every
possible memory, whether on earth, in the sky or
then below the sea level. However, while any
digital camera can be used to get pictures on
earth and in when traveling in the skies, the
underwater shots require specialized cameras.
Underwater photography is not just about
memories, but is an important aspect in the
research of marine life. Thus, marine biologists
require cameras to be placed underwater,
sometimes for days and weeks together in order
to capture all that happens deep down, below.
Whether it is ones hobby or profession one
needs to use a specialized underwater digital
camera. One needs to remember that this type of
camera is different from the typical water
resistant ones. The former can be used in any
level of water. While on the other hand, the
latter can only be used up to a minimum level.
Beyond that the camera is defunct.
For underwater shots and shooting one requires a
specialty camera with the underwater casing that
can withstand the pressures and temperatures of
the deep seas. It is these casing that have them
categorized as those meant for underwater
picture taking purpose.
However, when shooting underwater one needs to
keep a couple of factors in mind, which include:
The deeper one dives for shooting, the more
the light diffuses. This implies darker images
at increasing depths. This happens because the
red spectrum seems darker due to the light
diffusion. However, to counter this one needs to
use the white balance to bring up natural colors.
Subjects shot underwater appear larger than
their actual size. To prevent this the
viewfinder needs to be adjusted according to the
size one desires.
The underwater cameras with a built-in flash
would end up producing a marine show phenomenon,
with blurry pictures and white particles
floating above. In order to avoid this one needs
to ideally use an external flash.
Prior to actually using the camera underwater
it is advised to submerge it initially just for
a few minutes to ensure that there are no
leakages into the casing.
Ensure that there is no sand of dust particles
between the seal of the casing as the sand tends
to crystallize causing leakages.
Use the macro lens in case of capturing
smaller subjects. This way one can grab their
pictures without disturbing them.
Most underwater digital cameras come with
optional lenses. Don't be afraid to add these
lenses to your underwater digital camera kit.
Macro lenses will help you capture small things
without getting too close and startling your
subject.
