Electromagnetic radiation in the visible (Vis), infrared (IR), ultraviolet (UV), and X-ray range are applied for gaining information concerning the structure, genesis, and present state of artwork. The documentation can be carried out either by film or digital cameras.

The sketch shows the penetration depths of UV rays, visible rays, IR rays and X-rays into a cross-section of a painting. The penetration depth of electromagnetic radiation in a painting © INTK 

UV fluorescence images yield information of a coating (e.g. varnish) and retouching.

The same painting is shown once with normal light and once under UV light.  Hieronymus Bosch: The Last Judgement, The Paintings Gallery of the Academy of Fine Arts Vienna, visible and UV fluorescence image © INTK 

Underdrawings (concepts of the artist) can be visualized by infrared radiation.
