I saw this pic online and thought it was really cool. A lot of shots taken at high altitude lack depth because there is no obvious point of reference but in this photo because of the continuity of the plume of ashes and smoke you can clearly see the depth of the atmosphere including the different layers with the jet stream scattering the orginal column even to the edge of space, as well as the refraction effect at the bottom flattening everything like looking into a bath tub.
