T30. Anamorphic Images with Pinhole and Camera Obscura with Ana Angélica Costa

In this workshop, participants will explore the construction of self-made image-producing devices to create photographs beyond the traditional Cartesian perspective. The focus is on generating anamorphic images through direct interventions inside cameras built by the participants themselves. Through hands-on practice, students will work with the camera obscura principle to understand how images are formed, including the inversion and upside-down projection of light inside the device. The aim is to experience image formation as a physical and spatial process rather than a purely optical one. Participants will design and build their own anamorphic cameras, use them to produce photographs, and then develop the results in the laboratory. The session concludes with a collective analysis of the images, reflecting on distortion as an expanded way of seeing.
