Taken with a pinhole camera over 6 months. Amazing. More of this guy's work at http://www.pinholephotography.org/

There was something similar in the UK magazine Amateur Photograper a few years ago. They were pinhole images also of around six months exposure taken from high up on New York buildings. The arcs of the sun were not as dramatic as the one in your link but in some places they overlapped showing large areas of sky as total sun coverage.

The photographer had various problems to overcome such as finding dark enough neutral density filters and dealing with builders unbolting cameras during building renovation work.

Pretty good if it was handheld.

That's pretty neat. I especially like how you can get a timeline of the weather with the gaps due to clouds.

There is nothing new under the sun.

I do enjoy researching the roots of different processes and photographic techniques/methods. I can see now accounts of solar recording were published as late as 1839-1840, regarding Sir J. Herschel's methods. The British Journal of Photography No. 398 Vol XIV December 20, 1867 published the basics of CF Patterson's apparatus of 1858 for registering the sun's conditions throughout the day on photographic paper. By this time it was nothing new, but his technique was quite interesting.

Dominique Stroobant has been doing this for a long time - or at least, did it LONG ago. He would dig a hole in the ground, put his sensitive material (don't remember what it was), install a top with a pinhole, and record the transit of the sun for 6 month periods. It is well documented in Pinhole Journal. I can't offhand remember which issue, but the one I'm thinking of had to be in the mid/late 1980's. In the same issue, you would find his soft cameras that he hung in trees.

In this case, it is literally under the sun, as if everything were not!

How do you prevent overexposure? Do you cover it up during daylight? If you were to take an evening shot with the pinhole camera used, not knowing his aperture(maybe f175) maybe an exposure of 10 to 20 minutes. But 6 months and no over exposure?

"But 6 months and no over exposure?"

What's a month or two in the grand skim of things...
