Time travel on the instalment plan: The index and future form in building [PDF]

open access: yesPhilosophy of Photography, 2012
The contemporary architectural rendering, digitally engineered and published in advance of construction, has come to resemble an image of an existing building so closely that it is hard to tell future from past. In constructing an appearance of an existing lived reality, which previously arose from the camera’s re-presentation of the trace of past ...
