The resulting photograph is equivalent to one that would have been obtained from the same exposure station with an untilted camera. Multiple-stage rectification may be employed to eliminate differential paper distortion photographically. It is commonly used in recent restoration projects, for heritage documentation and three-dimensional visualization of the object. The technique is a much faster method for obtaining the 3D model compared to single-image or stereoscopic photogrammetry.  ]]></note></mads>
