It is hard to imagine a time when our sight was not bombarded with images of far off people and places, when one had to actually be in the presence of someone to see their face without it being filtered through the hands of an artist (or while sitting on a Seat of Seeing). Images allow us to render the very small, the very large, and the very distant; they provide a visual record of time and place; they move us and entertain us; they replace perception with reality. Images are acquired by Earth-orbiting satellites, interplanetary probes, subterranean robots, surveillance cameras in unmanned aircraft and on nearly every street corner, and our mobile phones. They are created using optical principles and magnetic fields, and images display what is “seen” in every corner of the electromagnetic spectrum.
