In "Tegmentum Beta," Donna Huanca combines oil paint and sand applied to a digital print mounted on canvas, creating a layered work that merges digital and analog processes. The piece exemplifies Huanca's practice of excavating and obscuring imagery through material accumulation, where the tactile addition of sand and paint creates a textured surface that complicates the legibility of the underlying digital image. This approach reflects her broader interest in how bodies, surfaces, and materials interact across technological and physical registers.
