TimeStretch

This series of images (9 meters and 25 centimeters long when printed with a resolution of 25 cm per minute) depicts a journey from my home in North London to the Hampstead Heath Lido, that is 47 mins.

The technique:
I made this image by strapping my video camera to my daughter’s pram so that it pointed 90 degrees to the left. Later I took a line of 1 pixel width from each frame and stacked them together.

How to read the image:
The top image has a duration of 1 minute. Each alternating dot on the ruler in the bottom of the picture is the 25th of a second. In the places where I was standing still the image is stretched, but moving objects might be seen clearly.
In the top image I was passing a bus and then waiting for the green light at a pedestrian crossing while the bus turned into the road. Then the bus stopped at the lights to let me pass. So we end up seeing the bus from three sides.
The bottom row represents 2 minutes of walking down a street. The length of the cars results from the relationship between my walking speed and the resolution (1 pixel per 1/25th second).
