Digital microscopy

Digital microscopy provides a magnified view of a surface, supporting and enhancing the results of spectroscopic analyses. It is used to assess the condition of the support and paint layers, document damage, and suggest the presence of pigment mixtures, layers, glazes, and alteration compounds. This technique is essential for revealing painting methods, such as the modeling of draperies and flesh tones. Digital images are captured under the microscope using various lighting setups, including normal light, raking light (where the light is positioned at an angle close to the surface), and transmitted illumination (with light positioned behind the page).
