The final result of these techniques, is the creation of a digital image of the complete artwork, or of a portion of it, where the numeric value associated to each pixel of the image corresponds to a point measured on the artwork.

Advantages such as the possibility of applying digital image processing and analysis, of quantitatively comparing different measurements and of storing data in indestructable databanks, make of digital imaging techniques a valuable diagnostic tool for art conservation.

Moreover, they offer the inherent advantage of images: the gathered data retain the spatial information.

This allows immediate visual comparison among the results of different imaging techniques and a direct comparison with the objects analysed, as perceived by direct observation.
