The objective is to create a micro-environment - an illuminated dome with a constant geometry of illumination - to undertake non invasive observation of the surface topography of artworks. The dome is attached to a stereo-microscope, which is able to gain - at the same time - both colour and texture features of the sample. By using a stereo-microscope, a more detailed observation is possible. Important elements including colour, texture, the morphology of the sample surface, in terms of specular and diffused components of reflected light, can be summarized/condensed in the measure of Bidirectional Texture Function.
