The modern technology has been offering moreand more tools for digitalisation of historical artefacts orworks of art. Especially popular is a 3D visualisation, which allowsto 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 TransformationImaging (further RTI) seems to be a solution, which – beingrelatively inexpensive – offers a whole range of possibilitiesas 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 characterisedin this article, at the same time presenting subsequentstages within the procedure of obtaining images. In order toshow the results of this method, authors referred also to theirown experience in RTI. They described images by themselvesof three boulders with petroglyphs, which are in the possessionof the Archaeological Museum in Poznań. The authorspresented their own assessment of the RTI method – basedon their achievements and the source literature – identifyingits both positive and negative aspects.
