A 12 month exposure

"Symmetry"
Solargraphy. I took the photo with a pinhole camera which I built from a sewer pipe. It was exposured continuously for one year, which made it possible to register the path of the sun in the sky (1 line = 1 sunny day).

Looking at this guy's FB page, it seems this was taken in Gdansk. I can't seem to find how he built the camera, however.

He has lots of other examples, but I believe this is the only one with a 1-year exposure.

Neat stuff.

Well, he says it's a pinhole camera that he built with a sewer pipe, so I'm guessing it's very, very simple. However, here are some reasonable assumptions:

He either machined a ridiculously small aperture down to the micron, or used film with a stupidly low ISO, or both. I can't see how you could use digital camera for this and still call the camera a sewer pipe; if that were the case, the pipe would be more like the lens. (easier with film, too.)

The thing is, though, when you go down that low, you're in the land of "impossible to check your work."

Might interest you to know George that I screwed around with 0.5 ISO film that was originally intended to make slide projections from X-ray sheets. So, even in clear summer sunlight, the exposures were quite long.

But the problem is that exposure compensation isn't a perfect science. There's still variability from outdoor temperatures, the age of the film, etc. Maybe he fixes these up after he scans them?

A lot of thought went into these.

I mean, it's pretty good but it's just a building. I would be more impressed if he paid someone to stand there for 12 months.

Maybe he did. You can't trust anybody nowadays.

I thought it was interesting story about one of the very first photograph, of a street scene in Paris (1839)

It looks so empty, when in reality, there were lots of people in the photo. But, because the exposure was so long, the moving people did not show up.
