The liveliness of the matter linked with the memories we often place upon objects and photographs, stimulated me to create visual riddles. To me, rocks act as palimpsests: a surface that rises to the surface. Enlivening the objecthood of the image, I made rocks with photographs printed on paper. I used photogrammetry as a tool for experimentation. Photogrammetry is a methodology for archiving that 3D scans physical objects by taking photographs. Instead of being interested in the final image, I focused on the process of this technology. I challenged the limits of this methodology using translucent and reflective objects such as mirrors, to highlight the elements of chance and mistake. The images were used to create interactive and generative photographs: photographs that have an autonomous life which is activated by the presence of the viewer.
