From the Sensor to the File
Lecture delivered at The Reel Thing XLVI technical symposium, during the AMIA Conference in Baltimore, Maryland, United States of America, on 13–16 November 2019.
What is the journey from the signals generated by a sensor to the data actually written into the file? This presentation focussed on the particularities of Bayer sensors. The wast majority of contemporary film scanners use Bayer sensors due to the many advantages they offer as capture devices at the interception of media workflows. The presentation adresses a method for using Bayer sensors to digitise at half resolution but full RGB. This scheme offers a way for archives with very limited funding to digitise economically but at high quality.
