Underwater Photography Tips
Underwater photography
produces some of the most eye-catching and unusual images around, but they are
a challenge to shoot and require some fairly expensive equipment. Practicing
the technique beforehand, especially if you have a once in a lifetime trip is
the key, as is being comfortable in the water. Here are some ideas on how to
get those underwater photos.
1.Practice
in a Pool

Before attempting
underwater photography in the ocean, where the water is unpredictable, try
taking images in a pool. You will need a specialty underwater housing. Most of
the popular point-and-shoot and DSLR cameras have available plastic cases which
seal in the camera and the lens. These are watertight and are essential to
protect your equipment. Keep a polarizer filter attached as this reduces flare
and unwanted reflections from the water.
2.Catch
the Action

Practice holding
yourself underwater for longer periods of time and holding the camera steady.
Use a low ISO setting to get a fine grained image and a shutter speed of
1/250th of a second or more. You can use on-camera flash when shooting in a
pool to freeze the action. Wear goggles if you can’t keep your eyes open
underwater and try to capture a fun portrait with the person swimming or
floating in the water.
3.Split Underwater Photos
The major technical challenge faced by photographers while taking a split over the water and underwater photo is that the exposure value of the image above the surface is often different from the one under it. This occurs due to refraction under the water, which affects the overall focus of the above water segment. However, this can be overcome by using specialized “split diopter filters” designed to compensate for this problem.
4.Keep it Steady

To keep a camera
steady underwater is a challenge for anyone, because water is always moving. It
helps to practice snorkeling, and be comfortable with the water before attempting
to take images underwater. You need to be able to stay still in the water even
when fish or other creatures come to investigate you. Don’t be afraid to use a
friend or a rock to stabilize your body so you can hold the camera still,
though holding the camera with one hand is not recommended.
5.Lighting

When taking photos
underwater you will need to use a specialist underwater flashgun called a
strobe. These will be sold at the same place you buy your housing; a
conventional flash will not have the power to travel through murky sea/ocean
water so you need a strobe. Set your ISO as low as possible as the low light
conditions will give grainy images; choose ISO 50 or 25 if this is an option on
your camera.
6.Zoom
in for Details

Macro photography when underwater can be used to obtain some stunning images. Use a macro lens (usually 50mm – 200mm) to be able to focus on subjects that are inches or centimeters away. It’s worth photographing the underwater images in RAW format, because it is best for images that you want to use color correction software later. Images in RAW format will still retain good quality after going through the color correction process.
7.Avoiding Loss of Color
One of the biggest
hurdles in underwater photography is the loss of color and contrast. While
submerged in the water, things appear to be blue or green in color. This is
because the colors with longer wavelengths are absorbed by the surrounding
water. The loss of color happens both horizontally and vertically, making
distant subjects appear colorless and vague. This problem can be resolved
either by getting as close to the subject as possible while using a wide-angle
lens for close focus, or using flash, which helps in restoring the lost color.

Recommended Settings
When shooting
underwater, choose the lowest ISO possible, so you get a fine grained image.
You will need a shutter speed of 1/125s – 1/500s to freeze the action – for
example a school of fish. Use a small aperture (f/11-f/20) to get objects in
the foreground and background sharp. Shoot in RAW mode when possible so that
color correction is easier later on.
9.
Recommended Equipment
You need suitable
underwater housing made specifically for your camera (usually made by third
party manufacturers; shop around for the best price and fit). You will need a
strobe flash if photographing deeper into the sea and in murkier waters. The
best lenses for underwater use are macro and wide-angle lenses. Telephoto
lenses are useless because they won’t allow in enough light for a clear image.
10.
Conclusion
Underwater photography
is a great challenge and it can be expensive. However, if you want to pursue
this as a hobby, you will need the correct equipment. Be patient and
persistent. Don’t forget about composition rules and focal points just because
you are underwater! Practice changing the settings on your camera underwater
too. You can practice when you are snorkeling or diving in the pool. Finally,
don’t be afraid to take your time. The unique shots will be worth it in the
end!
