Abstract: Using imaging systems sensitive to the visible and
infrared regions of the spectrum and through digitisation of
x-radiographs, the National Gallery in London is establishing a
digital image dossier for every painting in the collection and
recording each stage of conservation treatments.

These image dossiers form the basis of a collection information
system (the VERMEER system) developed at the National Gallery to
serve the needs of curators, conservators, scientists, and those
involved in the reproduction of images in the Gallery's information
systems and publications.

This presentation will describe the imaging systems used at the
National Gallery to acquire spectral images for technical analysis,
three-band colour images for documentation and reproduction,
infrared reflectograms and digital x-radiograph mosaics. The
integration of these imaging technologies and methodologies into the
Gallery's activities will be described. A series of case studies
will illustrate the use of different types of images in the
examination, documentation and reproduction of paintings.
