An investigation of the time-lapse process by the use of long time-exposures rather than a 'sampling' technique. The time-exposures had the effect of exaggerating the change in the colour of natural light, so that as a progression from sunrise to sunset, the film records imperceptible changes of light by strong shifts in the colour bias of the film emulsion itself. The fact that the camera shutter was open for the entire 16 hour period of filming, meant that a complete record of the landscape was made rather than a partial one.
