Multispectral Imaging

The laboratory at Art Experts employs advanced imaging technologies to reveal hidden details beneath a painting's surface. This non-invasive process is critical for understanding the artist's original intent and the work's conservation history.

We use a comprehensive suite of core techniques to analyze the painting layer-by-layer:

• VIS (Visible Light) documents the surface appearance as a reference.
• RAK (Raking Light) reveals the nuances of brushwork and craquelure patterns.
• UVF (UV Fluorescence) pinpoints varnish layers and areas of restoration.
• UVR (UV Reflected) detects faded inks and prints.
• IRCCD (Digital Infrared) uncovers underdrawings and artist revisions.
• IRFC (Infrared False Color) differentiates materials based on their spectral response.
• IRF (IR Fluorescence) specifically highlights cadmium pigments.
• IRTR (IR Transmitted) enhances underdrawings visibility.
• VISTR (Visible Transmitted) maps the transparency of paint layers.
• IRR (IR Reflectography) penetrates paint layers to provide high-resolution data

These applications allow Art Experts to verify the original composition versus later alterations, document the complete conservation history, and support technical art history research.
