Interior of Thomas Hill Standpipe
On the way back down I decided shoot a spherical panorama of the cap that covers the water tower. This is inside the roof area above the observation deck or promenade. It was so dark that I had to use my flashlight to see the index marks on my panning head. That steel drum in the middle weighs 3 tons. 24 iron trusses extend 40 something feet from the drum to the sides of the structure. The 24 beams at the top are 12" x 12" x 48" hard pine posts covered by 42,000 board feet of pine. The surface of the water inside the tank (1.75 million gallon capacity) is a few feet below the floor you see below.
Shooting data: 14mm, f/5.6, ISO 1250, 3 second exposures, 2 rows of 6 images, plus 1 nadir shot.
Equipment used: Nikon D700, Nikon 14-24mm f/2.8, Promote Control, and Really Right Stuff pano/gimbal head & BH-40 ballhead.
