Night Vision

I've been fascinated for a long time about how we can see in the dark, and how cameras can see in the dark. For instance, in the dark, if we close our eyes and open them for just a split second we can still manage to make out objects in the dark. If you are standing in the street you'll see a street light and a silhouette of a house, a car parked on the road, etc...

However if you take a picture in the dark for just a split second, you'll see virtually nothing. On the same hand, with a long exposure or a extremely high ISO (in the 20,000's or so, which yep you better believe cameras are at and above that these days...) you can actually see better than a human eye. That being said, I think there is a lot of complexity in that relationship to be discovered and explored. Here's a picture of my car, with a couple of lights reflecting off of it. By carefully finding the right exposure, I was able to capture exactly what it looked like through my eye.
