The last banner came from a photo you may have seen before on the site. It’s from my Top of the Rock series. At the top of the Rockefeller Center the glass windguards are built with camera-sized openings. They may be there to diffuse wind sheer at high altitudes, but they make clever slots for inserting digital cameras. Screens on the backs of digital cameras are the new viewfinders. Gone are the days of tourists holding cameras up to their faces and squinting through the tiny hole to get a good shot.
