Just came across those fascinating photographs by  Jay Mark Johnson, depicting our surrounding a bit different than we are used to. Basically, everything that is moving becomes visible and everything that is standing still shows up “blurry”. Here is a brief explanation of the slit camera technique he is using to record those images:
Johnson produces photographic images that challenge the norms of perception. Employing a process that is distinct from conventional photography, he creates works that merge the recording of space and time into a single, linear “spacetime” continuum. The resulting photographs are akin to both seismographs and electrocardiograms in that, as timelines, they begin on the left and end on the right. The horizontal length of the image conveys an uninterrupted and fluid measurement of a brief span of time, varying in duration from 10 seconds up to 45 minutes. Text by ACE Gallery
