I got this shot from the World Trade Center in 1988. I didn't have a tripod so I rested my camera on my Domke bag and used a jacket as a cape to reduce the reflection from the window. I tripped the shutter using a cable release. It was taken with a Pentax MX, with a 28mm Vivitar lens. I was shooting with Kodachrome 64 a lot back then, that would be my best guess. It was scanned with a Minolta Dimage Dual scanner. I had to do my best to get rid of a lot of light pollution in Photoshop 5. The exposure would have been f2.8 for 20 or so seconds. FYI, the Pentax was stolen, I gave a friend the scanner and I still have and use the Domke bag.
