Time mapping

By documenting the movement of light and shadow frame-by-frame, each time point of movement is separable. Several methods were experimented to analyse the sequential movement of light and shadow in order to precisely visualise the path trace. In time mapping studio work, the photos is taken per shot per minutes within the entire duration of 3-hour shooting in 3 different rooms. 15 frames were extracted from each set of photos and each photos has a 12 minutes interval. The time gap can be easily observed when the distance of frames is prolonged and the light movement gap becomes measurable.

Room no. 1 Duration - 2h 22m Interval - 1 shot / min Light Source - Sun light
















Room no. 2 Duration - 3h 8m Interval - 1 shot / min Light Source - Sun light
















Room no. 3 Duration - 3h 20m Interval - 1 shot / min Light Source - Sun light

the visualisation of light path

When these photographs are layered onto one another, the condensing of time gap can be shown into one single image. These digitalised time lapse photographs simultaneously presented the change of light and shadow path from time to time. The movement track also remapped the memory of one specific space during one specific period of time. The compressing of time in one sigle frame

Space mapping Space in architectural settings is the result of our entire perceptual system. As we walk through a room, our visual perception reveals the structure of the environment and our movement in relationship to the space. Since our perception is heavily biased by light, manipulating light influences our perception, which also reflects from our past experient to this world, to an architectural space. These photos remap the memory of one certain space at one certain point of time.

Projecting space and actual space Projection techniques are used to further examine the applicability of the gathered experimental footages to the present space. The room projection experiment restores the recorded light path back to the real structural space. The regeneration of memory path emerged the boundary between virtual and real. This allows one to reconstruct a new spatial interpretation to the existing space. The window projection experiment, on the other hand, uses a projector as the light source to create an artificial light path in space. By simulating the light trace, one starts to re-construct the memory of this rebuilt relationship between virtual and real space.

Projection films series were used to test explore the boundary of virtual and real space. Room projection and window projection are conducted to examine and extend the definition of the boundary of space. The projected space also creates an illusion based on our past perceptual experience. 1. Projection film series: the exploration of virtual and real 2. Room projection : the regeneration of original light path 3. Window projection : the simulation of artificial light path

Projection film series: corner

Corner 2m 28s, colour, silent, two films, 40s and 1m 48s

The sun path series film is projected on the edge wh ere the wa ll meets floor. The projected image moves from left to right along the edge of wa ll in order to simulate the original movement of the recorded sun path in two of my sun path series films. Th e wa ll so cket ap peared in the film se ems to become part of the existing wa ll and the projected image of shadows and wa ll creates an illusional extension to the real structure in space.

Projection film series: corridor

Corridor 20s , colour, silent, two 10s films

The bus series film is projected on a Ushape corridor. The projected space from the film follows the existing form in the actual space and this virtual space extends the real one.

Projection film series: split

Split 1m 11s , colour, stereo

The split series use mirrow to seperate the projected film into two parts. Half part of the projected image is reflected, reversed and upside down. The two projected images interacts and the characteristic of the figure and shadow is deformed at the same time. The shadow becomes the body of the figure and the figure becomes the supplement of the shadow.

Room projection series Room projection 1 In room projection series, several experiments have been conducted to trace back the path of light and shadow in the actual environment. The visualisation of this remapped light path memory in space starts to form a connection between virtual and real space. The projected space follows the form of actual space and is distorted by the shape of the real structure. The obscure boundary and identity of this actual and illusional space is unclear and hard to defined. The nature of the actual space also changes by adding an additional layer to the original space.

Room projection series Room projection 2

By projecting the trace back onto the physical space, the spectator is able to construct their own idea of narrative experience and follow the trace of things that one usually ignores in the existing space. The documentation can also be remodified by removing part of the quality from the original space and displacing it to another space. And the original quality of the space where it is projected on starts to dissolves and emerges into the film.

Window projection series Window projection 1 In window projection series, the projector acted as the source of sun light by manually replaying the light and shadow path back into space. The regenerated light and shadow adapted the form of window and is projected back on the space in both day and night time.

Window projection series Window projection 2 As the projector moves, the simulated light and shadow moves around the room and creates an artificial path. The changing degree of light path is manually controlled and the form of this artificial window is distorted by the existing structural space it is projected on.

Window projection series Window projection 3

The purpose of the projection is to regenerate the path of light and shadow and restore the presence back to the actual environment. The transformation of an imaginary shadow space into an actual space re-examined the relationship between shadows alternation and environment and recreate the memory of the space. Through interchanging the space, the displacement of rebuilt memory differs and obfuscate one's perception

This project uses light and shadow to discover the way to redefine space in time. The anticipated project development would direct at expanding analytical methods to improve the quality of light and shadow in time space and exploring how to combine the mechanism with projection techniques for presenting a different translation of design in space.
