Aerial Twilight

Compared to the previous twilight photo, shot from sea level, the upper sky here is darker, the dynamic range greater over the same arc-distance of the image. This is because I shot the photo from an aircraft at around 35,000 feet above sea level, which is in the upper troposphere in wntertime, and well-removed from the greater dispersion of light that occurs in the planetary boundary layer. Oh yeah, it was a fantastically beautiful scene, too.
