Ross Ching of Thrash Lab is currently working on a series called Empty America, a collection of timelapses featuring heavily populated cities seemingly devoid of people. Empty Seattle is the second video in the series, following the first timelapse of San Francisco. In the behind the scenes videos, Ching explains the editing techniques needed to remove the thousands of people and cars that pass though the shots, as well as the way he uses Google Maps to choose shooting locations due to their tight shooting schedule. You can watch Empty Seattle below, and for more Empty America videos and behind the scenes explanations, check out the Thrash Lab YouTube channel.
