On this episode we present five ways of using cameras: To save money (by using $10 cameras instead of $10,000 lidar), as an invisible camera (by hiding cameras behind smartphone screens), not using cameras at all (by creating entire people out of thin air), to fight the Notre Dame fire (by flying thermal cameras with off-the-shelf drones) and to take pictures from 45km/28mi away (by using cutting photo technology and computation to make the impossible possible).
