The original close-up and this new photo were taken from a narrow window on the 12th floor of the Xuanwen Pagoda. Judging from the photos, the Clark expedition was equipped with some advanced photographic equipment. The two original close-range photos shot with a 60 mm lens and a 170 mm telephoto lens.
