Three years and I have never seen a jellyfish in the open. Today there were dozens in the water. I was with a dive buddy not inclined to wait. So I shot on the move. Try to get focus and lighting correct upon a subject that is largely transparent. It’s theoretical and near impossible. But you have to love these point and shoot automatic cameras. And then Photoshop has an automatic setting to enhance the poorly saturated image. But you still have to have an image to work with. I got a few. Unlike National Geographic I don’t have to pick a single frame. Unfortunately I did not have to many frames to choose from. Nat Geo would have wanted another diver in the image too. That is for another advanced lesson.
