I was playing around with making a pano of the bay. The photo gets real far away, of course, so I brought up the loupe in Aperture and was pretty amazed at the detail. That will be the Trans-America Pyramid in the loupe which is, as Google says, about 21.5 miles from where I took this photo. Maybe a little less as the crow flies.

The actual photo is too big to post. Yes, I could make it smaller, etc. but I don't feel like it. This is, obviously, a screen shot. Kind of neat?
