The pigment use in the Tomb of the Reliefs (fourth century BC) and four other tombs (seventh to fourth century BC) in the Etruscan Banditaccia Necropolis near Cerveteri, Italy, has been investigated. We made use of X‐ray fluorescence (XRF) and Raman spot analysis, XRF imaging, infrared luminescence and photography supported by Dstretch contrast enhancement. We identified the use of haematite, goethite, calcite, carbon black, manganese oxide, Tyrian purple, and Egyptian blue, with the last three only found under the central burial place of the Tomb of the Reliefs. The tuff in which these tombs were cut proved to be a significant challenge for XRF analysis as the signals of Ca, Mn, and Fe vary strongly due to the heterogeneity of the stone, so that it is difficult to distinguish between signals from the tuff and the pigments. Finally, we show that lightweight instruments transported in check‐in luggage may not answer all questions on pigment use but do provide additional insights.

The automatic color equalization (ACE) algorithm, part of the Retinex-derived family of spatial color algorithms (SCAs), is an image enhancement algorithm that mimics the adjustment behavior of the human visual system (HVS). It is commonly used on a unique channel for black & white images or independently on the three channels for color images. In this work, we introduce a novel application of ACE on hyperspectral images, referred to as HyperspectrACE. Here the goal is not to introduce the most performing hyperspectral image enhancer in the field, but to discuss the performance of a qualitative model of human color sensation when applied on more than the standard RGB channels. For this reason, we present the test of the proposed approach compared with classic ACE and other classic methods, to assess the differences in image dynamic stretching and global and local filtering contrast adjustment.

“…After the local processing, a global rescaling maximizes the image dynamic. ACE has been successfully applied for fine art print [43] , wall painting [12] recovery, interfaces assessment [39] , and digital film restoration [6,38,41] .…”
