My wife at times will want me to take a photo that is half underwater and half above water. It is tough to do with a small lens on a point and shoot waterproof camera, with waves lapping up and down over the lens.Once I was so intent on getting a photo of sea slug underwater with the French Polynesian scene above water that I remained behind to try to get the photo over and over again. When I caught up with my wife and our friends, I was accused of spending so much time at the spot because, the said, there were some topless swimmers next to where I was. I never even saw them. I was concentrating on the sea slug.And that was the truth.
