The longest photographic exposure

In 2001 New York City’s Museum of Modern Art invited Michael Wesely, renowned for “inventing and refining techniques for making photographs with unusually long exposures,” to photographically document the comprehensive renovation to the museum’s Midtown building. From the summer of 2001 to the building’s completion in 2004, Wesely’s cameras captured the construction site with their lens open nonstop for three years!

I enjoyed this contribution by one person in the discussion over at Metafilter:

I saw these a few years back and had the staggering realization that I was right there in the photograph – when the pictures were being exposed I was working a block or two away from MOMA, and I had walked through its field of view dozens, possibly hundreds of times.

Obviously, I was in no way discernible or visible. But still: I’m in there.
