This section contains materials on ‘1/0’, a solo exhibition by Brian Ring, a Canadian artist who lived in Hanoi for several years starting in the mid-1990s. Starting from photographs made in Vietnam which were then digitally manipulated, he produced works using a number of different techniques and materials. The title of the exhibition refers to the role of digitisation in the production of the works and also their content – mainly walls, windows and doors that can be seen as open and closed, as opposites – similar to the use of 1’s and 0’s in the storage of digital information.
