Even though Im the one who stated that it was Desfors shot, I had my doubts (which I subtly made in my original post). Im going to wager that its not a Desfor photo. For whatever reason the possible misattribution occurred means nothing to me: What does is the photo.
Desfors style was to use a very shallow depth of field. His subjects were almost always in sharp focus while things just outside that field, including the performers own hands, would be outor just outof focus. An example of that style can be seen in a shot of Francis Carlyle that appears in Desfors book Great Magicians in Great Moments (1983). While Vernon is in the group of men watching (including Cardini, Rosini, and Loew), and it would have been very easy to have the entire group in sharp focus, Desfor didnt do it. Carlyle and Fred Kaps are crystal clear, but the rest are just (and I mean just) out of focus (see page 112).
The pool photo in question has a very deep depth of field. Even the plants and the window of the building behind the scene are in clear focus. The physical features and even the ripples in the water are sharp. To me, this makes the shot done in a style that Desfor didnt normally use. In his regular style, the girls would have been clear enough to recognize their beauty, but not ultra-sharp and the building behind them wouldnt be sharp at all. Its certainly possibleif Desfor is the photographerthat he composed the photo that way because it was what he was asked to do, but in my mind it just doesnt fit his style.
