From the man behind the camera:
"Construction had already begun when I arrived in the city in 2009. The site was a large hole in the ground with construction crews milling around pouring concrete for the base. I began exploring the city looking for views and locations that would serve as groundwork for this video. In 2011, I secured a location with unobstructed views of Lujiazui where I could just glimpse the tower peeking behind the 185m (607 feet) Aurora Plaza. I maintained a camera there for the next 4 years until the tower was completed. In the meantime I took hundreds of thousands of photos from various viewpoints around the city filling up around 8TB in the process. In all, over 1000 hours were dedicated to this project in exploring, shooting and post-processing. I used a variety of Canon cameras, lenses and motion control equipment to shoot. LRTimelapse (lrtimelapse.com) was used for de-flickering while Adobe After Effects and Premiere were used for editing."
The Shanghai Tower will open sometime in the next few months. Currently, you can only check it out if you're thinking about renting an office there.
