The examination methods used to ascertain the state of preservation and to verify the existence and extent of non-original parts of the pictorial fabric include the photographic technique in grazing light (RAD) and UV-induced visible fluorescence (UVF) technique.
Grazing light photography involves positioning the light source so that it projects the light beam almost parallel to the surface of the painting. This procedure highlights all the reliefs and depressions on the pictorial layer. Such a method also detects the presence of engravings or overlaps of colour, shedding light on the artist’s painting technique. When it comes to monitoring conservation status, this type of lighting makes accretions, bulges and gaps easier to notice.
