Ultraviolet

In this panel painting, the use of UV light revealed an extensive overpaint shown, in the right margin, as a dark area. The yellow milky appearance on the rest of 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

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.
