When taking a picture with a camera, the light that passes through the lens is burned onto the film by opening the shutter, and the image is recorded. Therefore, if the 'exposure time', which is the time to open the shutter, is set very long, the phenomenon that all the light contained in the angle of view is recorded occurs.

Regina Valkenberg, who completed her master's degree at the University of Hertfordshire in the United Kingdom in 2012, became interested in photography using classical techniques. Mr. Walkenberg attached photographic paper to a beer can to make it a pinhole camera, which was installed on one of the telescopes installed at the Bayfordbury Observatory , one of the university's largest educational observatories in Japan. And I forgot that I installed a beer can pinhole camera.
The beer can pinhole camera was discovered again in September 2020, eight years and one month after the shooting began. It was triggered by the discovery of a misplaced beer can by David Campbell, chief engineer at the observatory.
The following is a photo taken with a beer can pinhole camera that has been left unattended for 8 years and 1 month. The overlapping lines are the trails of the sun for 2953 days. The dome of the Bayfordbury Observatory is reflected on the left side of the photo, and the equipment for atmospheric science constructed during the shooting is reflected on the right side.
The photo with the longest exposure time recorded so far was a photo with an exposure time of 4 years and 8 months taken by Mr. Michael Wesley of Germany, so this photo is a big breakthrough. is. Valkenberg, a photographic engineer at the University of Burnett and Southgate in the United Kingdom as of 2020, said, 'When I used the same technique before, the photographic paper was curled up and spoiled by moisture. I didn't intend to shoot with such a long exposure time, but surprisingly the photo survived. '
