The Daily Parker

Politics, Weather, Photography, and the Dog

Seen over Chicago

I'm really, really tired, but I just had to post this:

Did I mention how much I love my new camera?

In fairness, my old camera could have done that, too. It's a 200mm lens on a 1.6x digital image chip, ISO-100, f/5.6 at 1/500. My old camera wouldn't have had the detail the new one has, but really, the trick to the shot was the tripod I've had since 1983. (Seriously.)

The moon is actually pretty bright. Its albedo—the amount of light its surface reflects—is about 9%, or about half of an average surface on Earth. So in full sunlight it should read about 50% of the light that it would read at noon here, and, would't you know, it does. In noon sun in the park I would expect about the same exposure. So in reality, the moon is a much duller grey than this photo shows.

OK, I'm off to sleep now. Tomorrow I'll reveal what became of my car while I was in Connecticut.
