Though certainly not the norm, occasionally some photos can come out grainy.
When an image is very dark, or very low contrast, the potential for graininess rises. In particular, when your camera is forced to boost the low light level that it captures, the image may become grainy. You may not realize this is happening because cameras generally make this boost automatically. And some cameras do this...
So just what is lightness and contrast?
In an image, lightness (or brightness) is the overall light level. The picture of an eel in a coral crevasse at 30 feet is a good example of an image without much lightness, unless you illuminate it with a strobe. A dolphin just under the surface can be an example of an image with high lightness.
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.
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).

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.
I loved this sponge with the look of a cookie monster. But if I had used me strobe(s) closer to the lens for front lighting, it would have lit up the sponge inside the “mouth” and “eyes.” I wanted...
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...
