New Pigments Checker v.5 – Translucent support for Transmitted Infrared

2017-10-09T09:59:02+00:00

We often examine a painting with transmitted visible light and infrared radiation.  In particular, Transmitted Infrared photography (IRT) is part of the Technical Photography documentation and allows to detect underdrawing and pentimenti. It is a very effective imaging method since pigments become even more transparent than in the usual IR photography method. So, we are [...]

Type II Super Lattice (T2SL) imaging technology for infrared reflectography (IRR)

2017-09-13T13:25:33+00:00

Read the new paper regarding imaging devices for infrared reflectography (IRR) : A. Cosentino, Type II Super Lattice (T2SL) imaging technology for infrared reflectography of polychrome works of art, e-conservation Journal 5, 2016. CLICK HERE Artistic paints attenuate and diffuse infrared radiation less than visible light and thus infrared cameras can be used to inspect polychromed [...]
