The hangar-turned-camera recorded a panoramic image of what was on the other side of the door using the centuries-old principle of "camera obscura" or pinhole camera.
The opaque negative image print was developed by 80 volunteers during five hours in a vinyl pool liner custom tray, the size of an Olympic swimming pool, with 600USgal of traditional developer and 1200USgal of fixer pumped into the tray using high volume pumps.
