“…Because this technology is a computer-based photography method that can illuminate a subject from all directions and angles, it is possible to obtain threedimensional visual information that cannot be obtained with ordinary photography. Currently, the Cultural Heritage Administration (CHA), Korea, uses this technology to record and preserve cultural heritage, especially in the fields of cultural heritage preservation, analysis, monitoring, and experimental archeology (Jo et al, 2021;Kim et al, 2023). For natural heritage, the CHA, Korea, first applied RTI technology to dinosaur footprint fossils from Ulsan earlier this year (manuscript in preparation).…”

A total of 64 specimens of trace fossils were collected from the Jinju Formation of the construction site of Jinju Aviation Industrial Complex, and from the Haman Formation of Namhae Gain-ri fossil site. The fossils are continuously and regularly meandering sinecurve in shape. The fossil varies in morphology: width between 0.2 and 5.6 mm, wavelength between 1.5 and 28 mm, and amplitude between 0.9 and 7.9 mm; the Jinju specimens are commonly wider than the Haman ones. The ratio of wavelength to amplitude is more or less regular regardless of width of the specimen, and the linear correlation of the ratios shows that the Jinju specimens fit better than the Haman specimens. Taking all morphometric parameters, specimens in all size ranges are temporarily identified as ichnospecies Cochlichnus anguineus. In order to obtain more distinct and clearer images of Cochlichnus, we selected two specimens and applied a new imaging technology RTI. For photography of the trace fossils, 50 to 80 images were taken per set with photometric lighting close to the surface and horizontally. RTI technology clearly showed that the images of tiny fossils were improved: the surface contrast become sharper and messy and unnecessary information disappeared. Currently, RTI technology is used in many fields including preservation of cultural properties and archaeology. As a consequence, we hope to apply this technique to the field of paleontology, especially to the study of trace fossils of very small size.

In this study, we examined the effectiveness of RTI(Reflectance Transformation Imaging) method as a digital imaging technology that can accurately and three-dimensionally record the damaged state of mural heritage. For this purpose, major damage types were classified on the mural painting in Josadang shrine of Buseoksa temple in Yeongju, and an RTI was conducted on areas with highly damaged areas. According to the results by the type of damage to the murals, salt weathering damage (58.9-18.2%), painting layer damage (37.9-13.0%), past reinforcement area (9.8-4.2%), biological damage and other contamination (19.8-2.5%), exposed damage to the finishing layer (19.7∼0.7%), past fixative area (2.5∼0.0%), and cracks (0.5∼0.3%) were found to have a high share of damaged area. From the RTI investigation for each damage type, image data was constructed to visually identify the degree of damage. In particular, in the case of microscope-based RTI, it was confirmed that it can be used as an accurate recording technology because it can identify color layer exfoliation, pigment particle shape, and salt crystal shape that are difficult to see in general microscope images. This is a research method that has not been attempted in existing RTI or mural research, and is expected to be applicable in the future not only to murals but also to the field of cultural heritage with painting layers.
