Mid-July 2013, the Sondor Resonances scanner was put to the test at the Sondor facilities in Zollikon with various film sound materials originating from the Netherlands Institute for Sound and Vision. Tonnie van Els and Paulo Fonseca (both of the Institute) were quickly instructed how to operate the scanner and tangible results from such sources as variable density and variable area material were obtained soon thereafter. In the picture on the far right, an Area of Interest can be seen, which can be selected to make sure that certain faulty areas are obstructed from the scan in order to obtain a better end result.
Our partner Sondor Willy Hungerbühler AG successfully scanned colored Gasparcolor soundtracks on their specialized scanner Resonances. The scanning is part of a research project by Andrea Krämer under the supervision of Prof. Martin Koerber, Hochschule für Technik und Wirtschaft in Berlin in collaboration with ARRI. Prof. Bernard Besserer of the University of La Rochelle supervised the scanning of several original nitrate prints of the Stiftung Deutsche Kinemathek. The soundtracks were pink/red and blue/green respectively.
