X (IR) refers to X-radiography and Infrared reflectography imaging techniques used in the conservation analysis of easel paintings. In this instance, the technical examination of  Seventeenth Century Dutch paintings by Rembrandt and Vermeer.

 These two forms of technical imaging are used by conservators to evaluate how a painting is best to be conserved or restored. They respectively reveal a paintings structure - crossbars, nails and canvas weave,  and the paint layers with all the possible underdrawings, erasures, revisions and previous restoration acts. In addition to their central analytical purpose these technical images also compress layers of time and reveal earlier stages of the paintings production, everything being equally visible at once.

The drawings in this exhibition is concerned with the complexity of time in an artwork when it is manifested through x-ray and infrared imaging and the temporal tension it reveals between what is hidden and what is visible.
