[vc_row][vc_column][vc_column_text]Imaging is a type of examination, often prior to physico-chemical analyses, with the aim of better understanding or visualizing an artwork.<\/p>\n

It allows us to understand the technology implemented during the creation (preparatory drawings), the genesis (e.g. repentances), or the material history (composition and distribution of pigments) of an object.<\/p>\n

At CARAA we have different techniques and cameras that allow us to examine the work from the deepest layers (the pictorial support), to the most superficial layers.<\/p>\n

Ultraviolet fluorescence<\/strong> imaging as illustrated in this image of a 17th century Indian painting allows you to visualize late restorations but also the UV fluorescence highlights of the materials and pigments present on the painting.<\/p>\n

Finally, multispectral imaging<\/strong><\/a> corresponds to the acquisition in reflection between 360 and 1100 nm and therefore makes it possible to examine the aertwork in the entirety of this spectral zone. A \u201ccube\u201d is then generated and allows the characterization of the different pigments according to their relative reflection over the entire area examined.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″]
