The history of darkness underpins the history of illumination. That the Lunar Society called itself so, among the enlightened of the west midlands, because they could only meet on nights of the full moon when there was light enough to get home. Memories of nights too dark to see: Dartmoor, Auchterarder, Waterville . . .The dark still existed, even in overlit Britain.
Dust in the projector beam
Scratches on windows
Smears on mirrors
The mote in your eye
The maculation of vision is permanent, as integral to sight and to the mediation of vision as light itself. To complain about codecs is as futile as to complain about the acuity of your own eyes?
And yet: one of the great reasons to undertake this work is the weighty metaphor of blindness: the blind hand of the market, the sightless measurements of social physics, the "denigration" (unfortunate term) of vision. To restore to sight, and by implication to the senses, their place in the world, antagonists of its mathematicisatiomn, immaterialisation and spatialisation.
