Darren Samuelson has done a really great device – some might even say he made a great camera great. The thing weighs 70 pounds takes a lot of maneuvering and mathematics to function while the objective to Old Timey accordion bellows. Despite these difficulties, however, Samuelson toured the U.S. with the platform monster in tow, shooting in this country from coast to coast in black and white . After the break, check out the video camera in action at the U.S. Space and Rocket Center in Huntsville, AL. You can also see some of his progress and pictures in the source link below.
