Współczesna technologia oferuje coraz więcej narzędzi służących do digitalizacji zabytków czy dzieł sztuki. Szczególnym zainteresowaniem cieszą się zwłaszcza wizualizacje 3D, które pozwalają na bardzo realistyczne odwzorowanie przedmiotów. Dla wielu instytucji kulturalnych i naukowych, w tym także muzeów, narzędzia te mogą być jednak trudno dostępne, głównie ze względów finansowych. Prezentowana w artykule metoda obrazowania z przekształceniem odbicia (ang. Reflectance Transformation Imaging, dalej RTI) jest – jak się wydaje – rozwiązaniem, które przy stosunkowo niskich kosztach oferuje bardzo duże możliwości w zakresie dokumentacji zabytków. Pozwala ona bowiem – bez konieczności używania specjalistycznego sprzętu – tworzyć obrazy 2.5D ze zwykłych fotografii cyfrowych. W niniejszym artykule krótko scharakteryzowano istotę działania metody RTI, przedstawiając jednocześnie kolejne etapy procedury uzyskiwania zobrazowań. By zilustrować efekty metody autorzy odwołali się również do własnych doświadczeń w zakresie obrazowania RTI. W tym celu opisali wykonane przez siebie obrazy RTI 3 głazów z petroglifami, które znajdują się w Muzeum Archeologicznym w Poznaniu. Na podstawie własnych działań oraz bazując na literaturze przedmiotu autorzy zaprezentowali własną ocenę metody RTI, wskazując na jej pozytywne, ale i negatywne strony.

REFLECTANCE TRANSFORMATION IMAGING. ABOUT A PHOTOGRAPHIC METHOD FOR DOCUMENTATION AND ANALISIS OF HISTORICAL ARTEFACTS

The modern technology has been offering more and more tools for digitalisation of historical artefacts or works of art. Especially popular is a 3D visualisation, which allows to obtain a very realistic image of the subject. However, for many culture and science institutions, including museums, these tools are not easily available due to financial reasons. The discussed herein method of Reflectance Transformation Imaging (further RTI) seems to be a solution, which – being relatively inexpensive – offers a whole range of possibilities as far as documentation of historical artefacts is concerned. It allows – without the need of using a high-tech equipment – to create 2.5D images out of regular digital photographs. The way how the RTI method works has been shorty characterised in this article, at the same time presenting subsequent stages within the procedure of obtaining images. In order to show the results of this method, authors referred also to their own experience in RTI. They described images by themselves of three boulders with petroglyphs, which are in the possession of the Archaeological Museum in Poznań. The authors presented their own assessment of the RTI method – based on their achievements and the source literature – identifying its both positive and negative aspects.

All periods of Egyptian history are represented at Gebelein and it encompasses many kinds of archaeological site found in the Nile valley (that is, cemeteries, settlements, fortifications, temples, rock quarries etc.). The area was a significant centre in the history of ancient Egypt, but its exact role and the reasons for its importance still awaits explanation. That is why the Gebelein Archaeological Project was initiated. The field survey of Gebelein, which started in 2014, aims to recognise the topography of the area and the degree of destruction of the sites and to locate archaeological remains as well as to determine their interpretation and dating. This report outlines the results of work conducted during seasons 2014, 2015 and 2016, which encompassed the archaeological and epigraphic field surveys, geophysical prospection as well as work conducted in the rock-cut chapel of Hathor.

Fieldwork in early 2019 by the Gebelein Archaeological Project encompassed surveys of two cemeteries situated south of the ancient town of Per-Hathor/Pathyris in the area of the Eastern Mountain of Gebelein. One of these is dated to the Old Kingdom and the First Intermediate Period, the other tentatively to Fatimid times. The third survey searched for local chert sources on the Western Mountain, investigating a local tradition of lithic tool production.
