Marking the 75th anniversary of “The Wizard of Oz,” Warner Bros. recently released a 3-D remastered version of the film which and launched a comprehensive, cross-divisional campaign encompassing theatrical, home entertainment, consumer products and a number of promotional partnerships.
The 3-D conversion was a long and complex project which Warner Bros. initiated with a very high resolution scanning of the original Technicolor camera negative. The restored 2-D image then was transformed by creating a depth-map of each frame to construct 3-D imagery and determine distances from the viewer’s vantage point. This was followed by the long process (with the use of a rotoscope) to further refine viewer distances and fully layer shapes and objects.
“People have asked for years about ‘The Wizard of Oz’ 3-D conversion. My answer was always, ‘We’re not doing it until it’s perfect.’ And now it is,” said Ned Price, Warner Bros. technical operations’ vice president of mastering. “As a kid, I was so enthralled by this film. Watching it, you just want to enter the frame, enter the Land of Oz. This new version will allow you to do just that.”
