The slide shuts down-or de-activates–at night. Or in the dark. No one knows for sure. Several months ago during inventory of the slides holdings in bunker #11 one of our head archivists found herself suddenly lurched into darkness when the power cut-out during a violent electrical storm. We have all been trained to carry back-up night-vision goggles when in the bunker archives (who follows such protocols?) and so, and thus.
Can’t you imagine, for yourselves, what happened next? The archivist donned her goggles to continue her work when she noticed that–faintly illuminated by the red light of the emergency exit sign–each of the slides before her bore faint traces of their images, except for one. One that had shut-down, de-activated, or gone to sleep in the absence of direct light.
Also, time seems to pass in the image, although we have only just begin to document this. That is, the objects in the slide remain stationary, but appear to age, to decay, in real-time. We first noticed this with the two bushes on the easterly side of the house at far left, bushes that slowly turned brown (the effect of drought?) after several weeks.
But it is the first phenomenon–the shut-down–that captures our attention. The fact that the images de-activates or sleeps as a (hopeless) act of preservation against, it appears, time itself.
