What Happens When You Take a 10 Million-Second Exposure of the Sun?

What’s the longest exposure you’ve ever taken? Thirty seconds? A few minutes? Check out this camera that shoots a ten million-second exposure of the Sun — depending on how long you leave it tied to your roof.

Matthew Vandeputte is well known for his time-lapse and hyper-lapse photography and has been making the most of his new flat overlooking the rooftops of London. This vantage point offered an ideal opportunity to try out solargraphy using a solarcan, a camera that is effectively a tin can containing a sheet of photographic paper and a pinhole. Vandeputte pointed it at the Sun for four months before rather nervously checking out the results.

Solarcan is a small company based in Scotland but ships its pinhole solargraphy cameras worldwide. There are also distributors around the world, including B&H Photo where you can pick up a single can for $19.99.

Solarcan launched 4 years ago on the back of a successful Kickstarter and has since made, sold, and shipped more than 13,000 cans. The northern hemisphere is little more than a month away from the summer solstice which could be a great time to set up for your first exposure.

Thanks for sharing my video, Andy. Much appreciated!

10,000,000 seconds? You need a Lee FIlters 15 stop IRND and a supercomputer to calculate exposure

one word. fixer
