It's difficult to believe that a photographer is capable of successfully creating a three-year long exposure on just one single frame, however, German photographer Michael Wesely shows that it's possible in his series entitled Open Shutter. Wesely has spent much of his career working on camera techniques that allow this process to be done. In the mid-1990's, he started capturing building projects and architectural development with long exposures over the course of years.
The final result is a photograph consisting of ghosts of building construction, sun streaks, and trails, along with remnants of people and things passing through the scene over the course of time. Each photograph is a living memory of the time, place, and the people who passed through the space, while the surrounding buildings stand crisp and clear, never changing across the years.
