Abstract: (2291 Views)

Restoration of historical monuments relies heavily on comprehensive documentation conducted both before and after conservation and restoration processes. This study focused on documenting the cleaning process of Iran's Salt Men through the integration of various photographic techniques and specialized focus stacking software. Specifically, it examined the documentation of Salt Man, No. 1, housed in the National Museum of Iran by utilizing a combination of focus stacking and panorama techniques. The project aimed to produce high-resolution images from 5 different angles, capturing the complete depth of field before and after cleaning. The largest image generated in this project boasted a pixel density of 649.4 megapixels, showcasing the frontal view of the artifact. Several challenges arose during the project. The presence of hair on the head and face of Salt Man, No. 1, posed difficulties in photo alignment. Additionally, documenting the gold earrings using macrography presented another set of challenges. It is important to note that the documentation, conservation, and restoration of the artifact were carried out simultaneously. Consequently, close coordination with other members of the conservation and restoration team was crucial and meticulous recording of lighting angles, camera settings, and photometry were prioritized. Detailed documentation was carefully recorded both before and after the cleaning process, taking special care to note the conditions during photography and ensuring accurate color, light, and texture matching. This comprehensive approach established a robust foundation for artifact's future scientific monitoring.

Keywords: focus stacking, photogrammetry, high-res images, photography, natural mummy, depth of field.
