Current advances in imaging techniques allow for fast, easy-to-use, non-destructive instrumentation that can be routinely used to identify, understand, and predict surface alterations. To this extent, this thesis exploits Reflectance Transformation Imaging. This technique can accurately describe a surface’s appearance by collecting multiple images of the same scene, varying only the light positions around an object. The main interest is to propose methodologies for detecting surface optical properties, tracking their change over time, and isolating information related to surface changes. These methodologies are examined on cultural heritage metal objects to propose new conservation documentation tools for automating current processes. These tools can help identify the surface’s appearance characteristics and detect when and where a change occurs. Examples of corrosion evolution and cleaning treatments demonstrate their application.
