The longest photographic exposures in history

I am starting a new section of my blog. Naturally, I come by various interesting articles, photos, etc. Some of them are particularly fascinating. And so they will be mentioned here.

This is truly fascinating. It never occurred to me even to think of 3 years long exposure through the pinhole. It is somewhat similar (at least in my mind) to Hubble Deep Field observations but instead human life is being observed, not the starry sky.

Fascinating indeed.
