I was shooting some stock pictures by a museum in San Francisco and sat down to rest, looking at the wall facing me. I shot some pictures of people passing before me with my analog film camera Nikon F5. I liked the way they were entering and exiting the frame. I decided to come back with a digital camera and shoot several different pictures to put together in one single image. The whole shoot lasted one to two hours. I liked the idea of capturing one or two seconds of the lives of several unknown persons passing by the exact same place: in front of a wall, the “Walking Wall.” I used a Nikon Coolpix 990 on a mini-tripod. The pictures were shot in JPEG format, processed and put together in Photoshop 6. I used Cumulus 5 to put the sequence together like on a lightbox, Photoshop for the final layout and an Epson 1270 printer.
