X and Time
X and Time: a dimensional exchange Seale's camera exchanges the horizontal spatial dimension of X with the dimension of Time. This is done by imaging only the Y axis (a vertical line of pixels) of the same scene over and over again, up to 500 times per second. The internal processor of the camera arranges these pixel columns side by side, building up the horizontal dimension of the picture plane over time. The images are time exposures in one dimension and snapshots in the other.
In contrast to traditional photography, only moving or changing objects register clearly and still objects are rendered as blurs across the picture plane.
