Britain from Above (WAY above)

"A new BBC series makes use of satellite technology to create stunning images of Britain from above. Mark Sanders reports. Andrew Marr presents the series Britain from Above, the first episode of which will be broadcast on Sunday 10 August at 2100 on BBC One. "

Video and photo have always had a strange relationship. Sometimes a video can show things that a photograph can not, but sometimes a photo can show things that a video can not. Specifically, a video is many, many photographs shown in rapid succession - one after another. What you see looks like smooth motion, but every frame (still image that makes up the video) shows only one moment in time. There are a couple ways to alter this - slow motion takes many more frames, and then plays them at a slower speed, so what we see on video appears to happen slower then it does in real life (in some cases,thousands of times slower - like popcorn popping.) Video can also be done in time-lapse, where frames are removed, so that action happens faster then it does in real life - such as taking the construction of a building shot for a year, and condensing it down to an hour-long video.

This video take yet ANOTHER approach. This video tracks the flight paths of airplanes, the connections of cell phones, and the paths cabs take through London, and shows it on a map. Eath path is shown by a line drawn on the map, like the path was actually drawn on the map. But instead of leaving each path on the map, even long after the airplane has landed, or the cab reached its destination, the paths fade away after a time. The result is a great composite, and a really cool video. Check it out here
