MULTISPECTRAL IMAGING

We utilize a wide array of special photography techniques to look below the surface layer of a painting, including:

VIS — visible photography provides pictures of the work that acts as a backdrop for comparison with other multi-spectral representations.

RAK — Raking light allows for the documentation of aspects of surface topography and painting method, such as craquelure and brushwork.

UVF — Ultraviolet Fluorescence When a work is exposed to ultraviolet radiation, traditional or older varnishes give off a different color than retouches, making it possible to tell the difference between an original work and one that has been retouched.

UVR — Ultraviolet Reflected uses reflected ultraviolet light allows one to see fading ink and prints.

IRCCD — Digital Infrared Reflected allows one to see the underdrawings of paintings and pentimenti, or alterations in paintings.

IRFC — Infrared False Color is created by combining a visible picture and an infrared picture, thus making it possible to observe the different materials and retouches in the false color image.

IRF — Infrared Fluorescence makes the presence of substances like cadmium pigments visible

IRTR — Infrared Transmitted enables one to have a better visual representation of underdrawings and alterations, as well as certain paint layers that appear opaque to normal infrared light.

VISTR — Visible Transmitted allows the appearance of layers of paint and alterations by contrasting what is transparent and what is opaque in visible light.

IRR — Infrared Reflectography enables penetration of the paint layers in order to see the underdrawing, but the processing time is much longer than other techniques.
