Several years ago a helicopter dropped a photographer with a special camera on one of Switzerland's highest peaks. His spectacular photograph of a 360-degree panorama of the Alps was printed in a fold-out book and called the "Top of Switzerland." Now comes Mark Segal, an engineer-turned-photographer who has modified a camera made in 1916 to take similar shots. The camera sits on a special tripod and spins slowly in a circle while constantly exposing a roll of very long film. Segal can create a mural-like photograph of anything that could best be seen in a complete circle. Imagine a panoramic view of yours, the loveliest yard in the neighborhood. Or the drama at a cocktail party plump with beautiful people, or the warmth of all your friends gathered to wish you the best at your wedding. One additional delight: As the camera sweeps the scene, people can pop into different parts of the photo. How many people appear at least twice in the photo below?
