- Research focus Description
Statuette of Crouching Venus, dated to the 1st century BC. Place of discovery: impluvium of the atrium of the House of the Triclinium, V 2, 4, Pompeii. The statuette represents a well-known and widespread iconography: Venus emerging from the water, kneeling on her right leg, which rests on a small column, wringing out her hair. Her hairstyle is parted in the middle, with lateral strands divided like small serpents, culminating in two long braids.

- Method Description
Visible induced luminescence (VIL) is a technique belonging to the MBI photographic techniques. The object is irradiated with a source of radiation that does not include the infrared spectral band. At the same time, the modified camera with a dedicated filter collects the infrared luminescence of selected pigments, such as Egyptian blue.
- Tool / Equipment (or Software) Description
A modified Canon EOS 400D camera without the internal ICF/AA filter, Canon EFS 18-135mm, F/3.5-5.6 IS lens and a IR bandpass filter B+W 093 IR
Two Quantum T5D-R flashes, with the support of two QF80 Qflash UV/IR Wave Reflectors, provided with B+W 468 UV/IR cut

- ROI or target area or spot size
- 22.3*15.0 mm
- Examination Methodology
Each image is acquired in *.RAW format, which contains low-processed data to preserve entirely the information recorded by the image sensor. The image parameters are calibrated with a ColorChecker and a self-build target with Egyptian blue.
The image acquired is elaborated with a graphics editor program, saved in jpg file and rendered in black and white image where Egyptian blue appears like spots with high luminosity.
- Equipment setup - Experimental
f 9.0, time 1/200 s, manual mode, neutral balance, ISO 200
- Output interpretation
Egyptian blue glowing white if present
