OK, while we're on the subject of conundra (would that be plural of conundrum?) here's one to ponder: Gazing at one panorama of two 1920s baseball teams posed on the playing field I noticed that the shadow of one team is in front of them, but the shadow of the o ther team is behind the players. It was taken around midday because the shadows were slight. It didn't appear that the different shadowing was the result of two photographs because I couldn't see any seam. All the players and coaches were s tanding side-by-side. My only explanation was that this might have been taken with one of those rotati ng lens, and the teams were posed in a semicircle to get everyone in focus, so t hat put the sun on the faces of one team and on the shoulders of another. What d o you think?
