The analytical services that we offer include, but are not limited to, Photomacrography and Photomicrography, reflected and transmitted Infrared photography, Ultra Violet induced visible photography, and Raking and Transmitted light Photography.
Ultraviolet
In this panel painting, UV light revealed extensive overpaint, notably a dark area in the right margin. The yellowish, milky appearance across the surface indicates an old varnish.
Infrared
On occasion, a reflected infrared photograph of a painting, can reveal a preparatory drawing. The image to the left is taken with a regular camera and lightning, in the photograph to the right, the camera, prepared for infrared reflectography, cuts through the colors, especially the red that appears as transparent, to reveal the underlying preparatory drawing
Infrared
The canvas in this painting have darkened with oxidation and ageing. The inscription was barely legible as it can be seen in the first picture. In the one to the right, with the use of infrared reflectography, the photograph revealed the inscription with absolute clarity.
