Photos in Focus

Marine Cotte works in the European Synchrotron Radiation Facility, Grenoble, France, where her job is to support researchers in their scientific endeavours. A colleague asked for Cotte’s help to analyze some fragments of a photograph produced by pioneer of color photography, Louis Ducos du Hauron.

“I first used infrared microscopy, which allows you to scan two-dimensional regions, define the pixel size and then move from one pixel to another, acquiring an infrared spectrum at each pixel. In this way you can ascertain the molecular composition, as well as see where the molecules are distributed,” Cotte says. “Synchrotron infrared microscopy turned out to be very efficient for the identification of organic components, such as gelatine, celluloid, resin, oil, and so on.”

About the Author

Joanna Cummings

A former library manager and storyteller, I have wanted to write for magazines since I was six years old, when I used to make my own out of foolscap paper and sellotape and distribute them to my family. Since getting my MSc in Publishing, I’ve worked as a freelance writer and content creator for both digital and print, writing on subjects such as fashion, food, tourism, photography – and the history of Roman toilets. Now I can be found working on The Analytical Scientist, finding the ‘human angle’ to cutting-edge science stories.
