Abstract

This paper presents the recent developments of Reflectance Transformation Imaging (RTI) beyond the visible spectral area, with an emphasis on Ultraviolet (UV) RTI and in particular Reflected UV (UVR) RTI and UV induced visible fluorescence (UVF) RTI. A painted and incised ceramic vessel from the Archaeological Collection of the University of Southampton as well as fragments of Faenza maiolica ceramics from the Southampton City Council Archaeological Collection were used as case studies. Results indicate that a complete multispectral RTI visualization, including additional captures in the infrared and ultraviolet spectral region, can be a valuable addition to the examination protocol. In particular, the UV-RTI techniques, as advanced digital analogues of UV imaging, enhance examination of subtle variations of the outer layer that are not clear in the visible, reveal manufacture evidence and decay relevant to glazes and varnishes as well as episodes of the ‘museum’ life of the artefacts.
