The image shows a person swimming in a large indoor swimming pool. The person is wearing a green swimming cap and is in the middle of a backstroke stroke. The pool is filled with blue water and there are lane dividers on the right side of the image. On the left side, there are two diving boards with numbers on them, one labeled "4" and the other labeled "3". There are also a few other diving boards visible in the background. The image appears to be taken from a high angle, looking down on the person in the water.
