"After careful consideration we have decided not to progress with 3D coverage of the service on this occasion," the spokesperson tells Us. "There are a number of reasons for this, most notably the additional camera footprint in the abbey."
Patrick Harrison, press secretary to the Prince of Wales and the Duchess of Cornwall, elaborated on the Palace's decision, telling The Guardian that "there are a number of reasons for this, most notably...the relatively small (albeit growing) audience for 3D, and our desire to not be distracted away from negotiating and facilitating the optimal 2D, radio, photographic and online coverage of the day."
Still, a source close to broadcaster Sky -- who "thought they had it in the bag after filming a mock ceremony at the Guards Chapel in Windsor" -- hints that a portion of the couple's big day may still be shot in 3D.
"We're going to work out other ways to bring 3D to our viewers," the insider tells Us. "I would imagine the procession to and from the Abbey, and the balcony moments, etc. will still be shot in 3D, if possible. Only the ceremony in Westminster Abbey will be missing."
Not that Middleton, 29, has any time to worry about the technical aspects of her wedding. On Tuesday, St. James' Palace confirmed that Sir David Manning, former British ambassador to the U.S., is currently mentoring Middleton on foreign affairs and matters of the state. Prior to working with Middleton, Manning advised both Prince William and Prince Harry (since 2009).
