Not really... Ted Orland played a joke on Ansel one afternoon. He gained the cooperation of some elementary school students on a field trip to a mission. Distracted Ansel, got the kids in front of Ansel's camera, and snapped a photo of Ansel coming out from under the focusing hood, with the aforementioned class lined up in front of him.
The photo was used on Ted Orland's photographic truths poster.
The details in Ted Orland's book, "Scenes of Wonder and Curiousity". One of the best books about photography.....ever.
