One professor of electronics, turned amateur astronomer, has captured the visible changes to the lengths of the day, over a six month period, from the summer solstice to the winter solstice. What we’ll tell you is that he didn’t use a conventional capturing method!
This image comes from flat film exposed from June 18, 2011, to December 21, 2011 in the creator’s garden. The shortening of the days are traced from the summer solstice to the winter solstice, from photo right to photo left.
What’s remarkable is the device used to capture the movement of the sun, facing the Southern Horizon, over the half-a-year duration. Greg Parker fashioned his camera out of an old tin, tea caddy. Greg says this was unusual for him as he’s used to using his ‘beer can’ pinhole camera which gives a more distorted picture.
Here is another image taken using the tea caddy pinhole over the same length of time, this time taken from the professor’s study window. Of the photo, Greg comments: “…the almost vertical exposure line is a reflection off the window on that house over towards the left. I don’t know what the boomerang shaped exposure in the sky towards the right is.”
While you come up with answers, be fascinated and inspired by the star-sized achievements obtained from an analogue, small box-sized, camera!
