The week started with the 6th module dedicated to Documentation, lectured by Ana Almagro. Very interesting and brilliant lectures on Guiding principles for documentation. From observation to preliminary studies; Recording tools and techniques; Photography (How to take the best photos for documentation purposes); Photogrammetry and laser scanning; Photoscan; Recording unaccessible areas.
We practiced on site preparing a final presentation of a section of Chicanna’ structures. We took measurements and drawned the whole front of Structure I; we documented our case study photographically rectifying the photos for documentation purposes. We took pictures to use them in Photoscan preparing a 3D model of our case study. All very satisfying and exciting!
On Saturday, the last day of the week started module 7th: Diagnosis, with Nora Perez, Jose Luis Ruvalcaba and Javier Reyes, the same lecturers we had in the third week at the National laboratory of Sciences for study and conservation of Cultural Heritage (LANCIC) – Institute of Physics, UNAM.
We spent the day on site with an assigned case study and we worked again in group. We undertook some tests applying various techniques on the stone in the façade of Chicanna’ structure II in order to to study the stone physical properties such as colour, hardness, resistance (electrical resistivity), conductivity, absorption capacity etc.
