This nudibranch is pretty common where I dive. It means we see it. It’s not as though you don’t have to keep a sharp eye. And it is usually small. And it is not moving fast. And it is usually partially hidden. If no one is looking I might move it a bit to allow me to get my camera into a better position Shhhhh! Don’t tell. Charlie, a friend a buddy, a pilot with whom I flew, likes to get the whole subject in the frame. I find that I’m sometimes influenced by his notion. Though I had rationally discounted his idea much of my work is of the whole creature.
Lately, I’m trying for more detail. The rhinopores (horns) have striations. At high mag in macro, the depth of field is so shallow that focus is a problem And then this guy was truckin’ along. Yes, they move. Not fast, but they do. It ain’t easy to get a shot. And I would love to manual focus on the horn. But it’s not something I can do underwater. In a way it’s like getting all set and then the last thing you do is close your eyes and press the shutter. Unlike someone I know, I do not shake my finger when I press.
