Things reflected in the windows, people on the sidewalk, traffic, buildings across the street, signs of every sort, hand written to neon. Masses of light and dark, sunlight objects, a wonderful mess of things to try and organize on the spur of the moment. Almost like the improvising of a jazz musician as the light and objects change with every step.
Sometimes waiting for a person to walk into or out of the frame, or vehicles to move into or out of the picture. Or waiting for the flashing light to flash on or off. Coming back to a scene when the light was better, or when the rain would stop. A great experience for the picture maker. All found and never manipulated in the darkroom or on the computer.
I had been photographing store window reflections for many years in black and white. Some times with a 4 x 5 view camera on a tripod, often with hand cameras. Sometimes studiously composed with large format, and sometimes using the hand camera like a sketch pad.
