The article features several paintings from an exhibition in New York, that were examined using infrared reflectography and X-radiography. These are included in the study which also examined more general aspects of Ingres's painting technique. According to the article, Ingres prepared his paintings with lead white grounds over which he would sketch in his composition in a dry medium such as pencil or black chalk. This method is said to enable underdrawings and painted sketches to be seen using infrared technology. These paintings include "Madame de La Rue" and "La Belle Zélie," among others.
