Infrared (IR) and ultraviolet (UV) light are two of the most powerful non-invasive tools used in modern appraisal, authentication, and conservation. These imaging techniques reveal information the naked eye cannot see—hidden repairs, overpainting, inpainting, removed signatures, anachronistic pigments, varnish inconsistencies, and structural alterations that directly impact authenticity and market value.
DJR Expert Guide Series, Vol. 85 — How to Use Infrared & UV Light to Detect Repairs and Alterations in Art teaches you the exact professional workflow museums, conservation labs, and expert authenticators use to examine paintings, drawings, works on paper, mixed media, and decorative art. You’ll learn how to interpret fluorescence patterns, IR absorption signatures, pigment reactions, and surface behavior with clarity and confidence.
Inside, you’ll learn how experts:
Understand the scientific differences between IR and UV light and how each reveals different layers
Read UV fluorescence to identify overpainting, varnish changes, adhesives, and restoration attempts
Use IR reflectography to detect underdrawings, pentimenti, removed signatures, and concealed alterations
Distinguish natural craquelure from repaired or artificially created crack patterns
Recognize modern pigments, fillers, resins, and synthetic materials inconsistent with the claimed age
Detect patched canvas sections, concealed tears, filler, overbrushing, and multiple restoration layers
Interpret medium-specific clues across oil paintings, acrylic works, works on paper, prints, and mixed media
Identify when a piece requires conservation-level analysis such as X-ray, narrowband UV, or microscopy
Understand how the presence of repairs or modern materials affects appraisal outcomes and market value
Volume 85 gives collectors, appraisers, dealers, conservators, and art buyers a museum-grade diagnostic system for spotting hidden repairs and authenticity issues long before they lead to costly mistakes.
