Underwater Photography Tips by Clint Tackitt:
Underwater Photography Tips #1 - Objects Underwater Are Further Away Than You
Think They Are
Are you aware that the ocean acts like a gigantic lens? It
refracts whatever you see underwater at an index of 1.33. Hence, underwater
photographers should note that when they wear a mask or when their DSLRs are in
housings, objects that may seem to be only one meter away from them are
actually 1.33 meters away.
So what I'm trying to say is that objects you see underwater
are actually at a further distance than they appear to be in your eyes. This is
why you will have to be aware when focusing on underwater photography subjects.
Underwater Photography Tips #2 - Get Creative with Settings
We all know that setting your DSLR to automatic will make
things easier for you. However, be mindful that you should get creative. You
can make use of the different settings available for shutter and aperture.
Clint Tackitt is one of the experienced underwater
photographers. Using manual for underwater photography will be a great way for
you to experiment with what settings work well and doesn't work well underwater.
From experience, pictures will normally appear looking a little flat with
presets. This is simply because you adjusted neither the depth of field or
exposure.
Another thing that you might want to try out is to vary the
shutter speed settings. What this does is that it helps you gain control of the
background color. Let's put aside the thought of how fast your subject is
moving underwater and the use of the strobe for now.
Be mindful that using a slow shutter speed at 1/60 sec
normally produces a beautiful blue ocean background. However, using faster
shutter speeds like 1/125 sec will create a background color that is close to
black. Why is it so, you ask? Well, using faster shutter speeds allow less
light into the camera, resulting in a dark background.
Underwater Photography Tips #3 - Light Is Important
There you have it - light is indeed a very important element
in underwater photography. This is why it is of utmost importance that you use
an external flashlight or strobe. These gadgets will provide light while you're
taking pictures underwater so that all the colors of the spectrum are put back
together into your photographs.
When you conduct underwater photography attempts
without using external light, you will notice that the results of your photos
will be tinged with yellow, green, or brown. Be on the lookout for lights that
provide a variety of settings.
