in addition, gci "conducts scientific research on materials' composition." for example, a project on the conservation of photographs has as one of its objectives the creation of an "atlas of analytical signatures of photographic processes" which will provide "a precise chemical fingerprint of all the 150 or so ways pictures have been developed." as a part of that project, getty scientists once examined the world's first photograph from nature by nicéphore niépce. using x-ray fluorescence spectroscopy, reflectance fourier transform infrared spectroscopy, and other techniques during the 2002-2003 project, they found (for example) that bitumen of judea was present in the image.
