Video filmed by Guardian photographer Dan Chung entirely on a production Canon EOS5DmkII and adapted Nikon and Zeiss lenses using manual focus. The camera was purchased to use solely as a video camera with existing Nikon kit.

The film was shot an edited in about twelve hours directly after picking the camera up from a Beijing camera store and charging the battery.

Lenses used are:
Nikon 17-35 f2.8
Nikon 80-200 f.8
Nikon 85mm f2.8 shift lens
Nikon 16mm f2.8 fisheye
Zeiss/Contax 85mm f1.4

The camera was set to neutral picture style, sharpness all the way down and contrast at -2. Saturation was left alone.

Edited in Final Cut Pro, the footage was all converted to Apple Prores 422 using MPEG Streamclip because there were problems using the native H.264 Mpeg files. It was exported as a QT at 720p. There was no grading, exposure or colour correction on this footage.
