“…Given the fact that earth pigments are ubiquitous in archaeological contexts, as well as in works of art from ancient times up to the modern period, their precise characterization is of great importance for understanding the archeological and art historical record, such as: raw material selection and use, provenance (geological origin) and the technology of paint production. Important information, especially in terms of use, have been obtained via the numerous case studies performed over time on a large variety of artifacts: prehistoric rock art [6,15,16], ancient wall paintings [17][18][19][20], religious art [8,21,22], easel paintings [23][24][25][26] and so on. However, within these case studies, the analyses are often limited to the identification of the generic class of earth pigment used (e.g., red ocher), without any specific characterization of the mineralogical species present or of the geological sources.…”

Natural minerals and earths with coloring properties have been widely used as artistic pigments since prehistoric times. Despite being extensively studied, the complex chemistry of earth pigments is still unsatisfactory described with respect to their mineralogical and structural variability and origin. In this study, a large group of earth pigments from various geographical locations was investigated using easily accessible spectroscopic techniques and multivariate analysis with the aim to identify distinctive mineralogical and chemical characteristics of natural pigment sources. Portable X-ray fluorescence (p-XRF), Fourier transform infrared spectroscopy (FTIR) and fiberoptic Raman spectroscopy were used for the elemental, molecular and structural characterization of the investigated pigments. Diagnostic spectral features and chemical patterns (fingerprints) were identified and discussed with respect to their geological sources. Due to the occurrence of similar accompanying minerals, it was observed that the differentiation of red and yellow ochers is more challenging compared to green, brown and black pigments. However, for some of the investigated pigments, the presence of certain accessory minerals and/or of certain chemical patterns can have diagnostic value. Principal component analysis (PCA) of the FTIR and XRF data matrices showed promising results in terms of geological attribution, highlighting a promising tool for provenance research. The results of the study demonstrate the potential benefits of this rapid and nondestructive approach for the characterization and differentiation of earth pigments with similar hues coming from different geological sources.

“…Spectrofluorimetry (fluorescence spectroscopy) is a contactless method aiming to make objects (materials, pigments) fluoresce; that is, to emit photons with longer wavelengths (usually visible light) than incoming exciting radiation (usually ultraviolet), but unlike phosphorescence, visible light is emitted only under UV stimulation [95]. Spectrofluorimetry (and microspectrofluorimetry-if a microscope is involved) may be successfully applied in pigment identification [91,97] as well as in detecting hidden drawings and signatures [95] and micro defects such as scratches e.g., on a varnish layer [98].…”

“…Classes detected in laboratory conditions may serve as pigment libraries [124], which may be then used as reference for further field work [115,125,126]. A small number of spectral bands provided by multispectral imagery makes it possible to generate band composites from selected band sets, allowing for visual investigation of acquired data [98,127,128]. Eventually, selected sets of bands acquired by hyperspectral sensors may be also used in this way after the identification of most informative bandwidths [129], but still it is not a common approach.…”

All countries around the world are blessed with particularly rich cultural heritage. Nowadays, many researchers are exploring different methods for documentation, management, and sustainability of cultural heritage. The aim of this article is to review the state-of-the-art documentation, management, and sustainability techniques in the field of cultural heritage based on the case study in the Museum of King Jan III’s Palace at Wilanów. Various 2D/3D image and range-based methods are discussed demonstrating their applications and drawbacks. The geographical information system (GIS) is presented as a method for management, storage, and maintenance of cultural heritage documentation.

“…While physico-chemical investigations deal with the chemical inspection of the surface layer's compounds (Ghervase et al 2018), modern imaging documentation is about replicating in digital format the artwork's physical surface, structure and chromatic characteristics. There is a plethora of non-destructive imaging methods differentiated by the electromagnetic spectrum range where they actually record data: X-ray, ultraviolet (fluorescence), visible, near infrared, infrared etc.…”

<p><strong>Abstract.</strong> In this paper we are presenting our approach and workflow for macro photogrammetry as a complementary method for 3D digitization of polychromies on wood support. Macro photogrammetry can be used for detailed documentation of physical damages in painting layers, underlayers or support. For a better presentation of the context, a selection of typical physical damages, relevant to this study, are explained. Two case studies are presented. Two wooden icons realized with different techniques and presenting different types of physical deterioration. The experiments detailed within this paper represent the first epoch of long-term monitoring of the restoration interventions for each of these icons. All the stage of our workflow is thoroughly detailed with acquisition parameters and processing settings in order to better understand the results and where things can be improved. For each icon a full body photogrammetry process is described, followed by macro photogrammetry on smaller selected areas on the icons' surfaces. Macro magnifications of 1&thinsp;:&thinsp;1 and 2&thinsp;:&thinsp;1 are obtained by using a dedicated macro lens and extension rings. Lighting setups and focus stacking process are also described for a better understanding of the parameters and settings used.</p>
