Some of these aspects are detailed in this report. The necessity for multidisciplinary collaboration to achieve results is stressed. A survey is given of various approaches to apply the method in art history. Preliminary results are briefly mentioned and suggestions are given for further work. The systematic comparison of underdrawings as revealed by infrared reflectography in paintings from a particular group would seem to be the most promising way. Grouping around authenticated paintings is shown to be possible and attempts to obtain a chronology based on underdrawings are reported. The possibilites to improve the infrared-to-visible image translation systems suitable for infrared reflectography are briefly discussed.
