This paper discusses two technical photographic methods based on the use of ultraviolet sources for art examination: Ultraviolet fluorescence (UVF) and Ultraviolet Reflected (UVR). While the first imaging can be realized with any digital camera, UVR images are acquired with digital cameras modified to be full spectrum since their sensitivity is extended into the ultraviolet region until about 360 nm. This modification consists in the removal of the in-built hot mirror filter on the CCD or CMOS sensor, which in turn renders it sensitive to ultraviolet and infrared light. This paper illustrates the procedures and the equipment to perform these methods discussing case studies and prepared samples.

Pigments Checker is a collection of 54 swatches of his­tor­i­cal pig­ments that have been applied using gum ara­bic as a binder on a cel­lu­lose and cot­ton water­color paper, acids and lignin free. This paper is not treated with opti­cal bright­en­ers, it’s slightly UV flu­o­res­cent, and it reflects IR. Two cross-hair lines, 0,2 mm (ver­ti­cal) and 0.4 mm (hor­i­zon­tal) are printed on each swatch of paper before the appli­ca­tion of paint, in order to have a means to eval­u­ate the pig­ments’ trans­parency in the IR and IRR imag­ing. Among all the pig­ments and their vari­eties ever used in art these pig­ments col­lec­tion select the most used ones from antiquity to early 1950’.
