Lookin' Sharper

Lookin' Sharper

While there are many techniques for sharpening, some yield better results than others.  We have selected one with a counterintuitive name...Unsharp Masking.  Why?  Because it tends to accentuate the important parts to the image without increasing visual noise or graininess.  

Unsharp Masking actually began as a clever technique to enhance the sharpness of printed images in the chemical/analog world.  Digital Unsharp Masking is uses a similar technique, and works something like this:

- It’s good to determine what should be sharpened, so edges are detected.  This is in effect “applying a mask” so that only those parts of the image that are significant enough to enhance are subject to sharpening.  In other words, those areas that may have small differences from pixels to pixels, like water in the background, are not subject to sharpening, while the intricacies the fish scales are sharpened.

- A threshold is applied.  If the change from one part of the image to another at an edge is small, the edge is not sharpened.  If the threshold is set high, only major transitions are sharpened.   In particular, if you are seeing graininess and pixellation, set the threshold higher.

Orange Photos

Orange Photos

It is always fun to add any new twist that you can think of for your underwater photography. I decided to experiment with things that were orange. I selected out lots of photos that I already had, and I also went on a few dives looking for anything with orange. I was very lucky and found my absolute favorite but elusive subject, the gaudy clown crab (Platypodiella spectabilis).

Use side lighting to make shadows

Use side lighting to make shadows

Don’t just use your strobes to light up everything. Sometimes you need to be careful how to use your strobes to NOT light parts of the image so that you can make shadows.

Turning a small subject into a dramatic photo

Turning a small subject into a dramatic photo

Have you ever wondered how people find these huge red finger sponges on the same dive where you saw only little ones? The answer is that these ARE the little ones you saw but photographed very close with an extremely wide-angle lens that includes everything within a 180º diagonal area. That means that you can stand very close to your 8 foot wall at home and get the entire wall from floor to ceiling in your photo from just a few inches away.

Lookin' Sharp!

Lookin' Sharp!

Have you noticed that your underwater images aren’t always as sharp as what you are used to seeing topside?  That’s probably because the water scatters the light bouncing off your subject.

 

If you don’t want to loose any sharpness due to light scattering, you’ll need to capture your photos in a vacuum.  Probably not very practical, and doubtful that your subjects would like it in any case.  In air or water, there will always be some redirection of photons by the molecules in between your camera and your subject.  The effect is more noticeable in water than air, due to the greater density of the water.  The Pros always say, “Get close,” and minimizing the light scattering is another reason to do so.

Why Are My Pictures So Blue Or Green?

Why Are My Pictures So Blue Or Green?

As Marshall McLuhan said, "The medium is the message."

While I'm not so sure he was talking about underwater photography, the principle is similar.  The medium in which a signal travels influences the information received.  This not only happens underwater, but topside is well.  The sky tends to be blue (where you dive...not here in Rochester, NY, where gray is the dominant color) because of the differing interaction between atmospheric molecules and wavelengths of light.  

Underwater, a similar effect occurs, and is more dramatic.  Sunlight entering the water from above becomes filtered by the water, and the reduction of red light is greater than that of blue and green.  So the deeper you go, the percentage of red in the available light becomes less and less.  Additionally, the distance between you and what you are looking at provides an additional filtration, removing even more of the red light.  

Actually, your camera (without flash) does a pretty good job of capturing the scene.  The blue/green cast you see in your pictures is a good representation of the available light that bounced off the subject and was captured by the sensor.  But your brain does a really nice job of automatically balancing those colors into a much more pleasing color balance.  "Eyes, this can't be right.  I'll fix it for you.  You're welcome, Brain."  It auto white balances for you, without any conscious involvement.  So what your camera records is not what you saw.
