Gorgeous. There are some things you run across with such rich color and texture and… Giant clams are pretty plentiful. The other day I saw one mating. How? Well they discharge the genetic material into the sea. It looks like a cloud. On the image it looks like dirt fogging the picture. So it does not amount to an image. And mostly they clam up when I approach. Ha, yes, humor, sometimes you gotta laugh. But some of the big guys don’t close all the way. And others just let you shoot. I have not heard if they are good to eat. But personally I avoid blue food. How giant? About a hand spread – hmmm maybe more – say 12 inches wide.
Have you wondered how the images are so sharp and color so brilliant? Good. Even with the water there, the image is better with careful white balance and being very close to your subject.
