| Abstract: | SUMMARIES. This paper presents the usefulness and utility of three complementary digitization techniques for the dynamic rendering of colour, roughness and shape of easel paintings. Twodimensional multi-spectral digitization and three-dimensional (3D) modelling of paintings are used for colour accuracy rendering and measurement, colour characterization, pigment identification, for high-definition visualization of the painting, and for the measurement of the shape of the support and the paint-layer roughness. The experimentation was performed on several paintings. The results show the advantages of each technique. Several viewers were developed to handle multi-spectral images and 3D models. CONCLUSIONS. Multi-spectral digitization and 3D modelling of easel paintings open new fields and techniques to investigate ageing, painting techniques, colour accuracy and high-quality printing. To perform accurate colorimetry on a painting requires multi-spectral digitization. To accurately measure shape and roughness necessitates 3D modelling. The association of the different digital techniques gives the user access to new ways of analysis and research for the conservation and study of painting material. The scientific museum community would benefit from adopting common technologies and techniques for high-resolution imaging as has already been done for indexing concepts and metadata. This could include common image formats, image analysis and visualization tools. Several records and large size digital prints will be presented at the next ICOM-CC meeting. |
