Split-level water portrait

An adult snorkeller floats at the surface of a clear tropical bay, the camera at the waterline showing her head and snorkel above and her torso and fins below in one over-under frame. No letters, words, signs or logos anywhere in the image. A real photograph, a fine-art over-under water portrait, made at the waterline through a fisheye lens behind a hemispherical dome port, deep f/8 focus holding detail above and below. One waterline band divides the frame: crisp and clear above, refraction-rippled beneath, the subject continuing unbroken across the boundary. The key is hard and sparkling on the dry surface, then absorbed and diffused into a soft glow under the waterline. Fine clean grain, true-to-life colour above, and the natural colour absorption of water below.
