Hartsfield-Jackson Atlanta International Airport - Between Concourses A & B

When we arrived in Atlanta from Philadelphia we walked instead of taking the train to leave the terminal. On our way out of Hartsfield-Jackson Atlanta International Airport we saw this art installation and made sure to give ourselves extra time to photograph it on our departure. This art installation is in the underground walkway between concourses A and B.
Again we alternated lenses and settings. These were all taken using a Canon Rebel T2i (550D). All photos were taken with fixed ISO of 100 and at Aperture Value of 9.0 using a Canon EF-S 10-22mm f/3.5-4.5 USM lens.
Looking at this and the PHL post it looks like the way the photos are uploaded and compressed they really muddy dark sections of the photos.

There are also rain and forest sounds being played on hidden speakers. If you find yourself at Hartsfield-Jackson Atlanta International Airport and have time I would recommend walking between the concourses.
