Imagine, walking up to a scene, setting your camera on a tripod, selecting the time capture feature from the feature set, and then keying in any date and time from the past 100 years, before finally taking a long (3-9 minute) time exposure that is able to capture a "light signature" that can not be detected by the human eye or most conventional optics. When the waiting is finally over, you are greeted (hopefully) with a usable image of that exact spot on the date and time you selected.
This, Ladies and Gentlemen, is the Time Camera.
Catonsville Junction Streetcar Loop near Baltimore as seen in late 1961 through the time camera, on a five minute and 40 second exposure.
