Just published Infrared Technical Photography for Art Examination.

A. Cosentino “Infrared Technical Photography for Art Examination” e-Preservation Science, 13, 1-6, 2016.

This paper discusses technical photographic methods based on the extended infrared sensitivity of a digital camera modified with the removal of the in-built hot mirror filter on the CCD or CMOS sensor, which in turn renders it sensitive to infrared light with wavelength up to approximately 1100 nm. This paper illustrates 4 methods: infrared (reflected light) (IR), infrared transmitted (IRT), infrared false color (IRFC) and infrared fluorescence (IRF). The procedures and the equipment are discussed using examples from case studies and prepared samples.
