Imaging Diagnostic on a 14 th Century Gilded Icon
This new paper is a valid example of the application of non‐invasive imaging methods (technical photography and multispectral imaging) before and after the conservation treatment of a work of art.

Infrared Technical Photography for Art Examination
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
Infrared Fluorescence Photography: Review
I noticed I often talked about Infrared Fluorescence Photography in my posts, such as the one on historical pigments, and the one on the Windsor & Newton Gouache color chart, but I didn’t properly introduce the technique yet. This post wants to be a brief review of the Infrared Fluorescence Photography. Infrared Fluorescence Some molecules and minerals
Infrared Fluorescence Photography: visible-only lamp
Visible LED lamps have an infrared component other than visible light. This infrared light gives a noise in the infrared fluorescence photography. White LED lamp emits Infrared roughly between 700 and 800. See Wikipedia; white LEDs are Phosphor-based LEDs and have an emission curve with a tail in the very close IR, see here. So, for a perfect IR
