Sunrise, sunset
This is beautiful.
A camera obscura was set up at the University of Hertfordshire’s Bayfordbury Observatory by Regina Valkenborgh in 2012, and in September this year the observatory’s Principal Technical Officer, David Campbell found it. The image depicts 2,953 arced trails of the sun rising and falling between summer and winter during a period of eight years and one month.

Meta? I'd say so!

That's very moving. And is surely the second best use of a beer can.

It's thought to have doubled the previous holder of the title,
According to the University of Hertfordshire, the German artist Michael Wesely is thought to hold the current record for the longest exposure photograph, captured over four years and eight months.

Re: Sunrise, sunset
There are some good ones of Eastbourne pier and Beachy Head, although they are only 6 months long.
