Blueprint is a project I started in 2020. The traditional diazo blueline paper - commonly used in urban design, architectural and engineering drawings decades ago, becomes my new way of identifying and photographing the ordinary scenes of the urban landscapes and ever-shifting transitions of the city space. Exposing the light sensitive papers to replicate the city infrastructures, leftovers on the construction sites, traces of human livings and so on, I create my own archive of urban blueprint with life-sized abstract blueline images in different scales and shapes. Then, the familiar architectural structures in the urban scenes are decomposed and dramatically transformed into mini-sized blueprint slices, waiting to be re-discovered and re-exanimated by the residents. By transforming the subtle changes happening in the urban space and trivial occurrences of human beings by this old-fashioned photographic technique, I also attempt to engage with the passage of time and the ephemerality of urban settlements.
