In a context of increasing social acceleration and visual overload, it becomes essential to question the capacity of images to resist oblivion and to continue shaping individual and collective memory. 

“30 minutos de matéria”, a video photo-installation presented in the group exhibition “What Lies Ahead” by first-year students of the 2025 PhD in Fine Arts at the Faculty of Fine Arts of Porto, is proposed as a laboratory of time and memory-images. The work invites viewers to contemplate, in real time, the slow decomposition of a printed photograph, challenging accelerated perception and calling for an expanded mode of attention.

Drawing on António Damásio’s notion that “images are the universal currency of the mind,” this article examines how the installation critically responds to the hyperproduction of visual stimuli in contemporary culture, while also exploring the intersections between art and science in the field of temporal perception. It further integrates a reflection on post-photography and the urgent need for a new “ecology of attention” in the face of increasingly fragmented memory.

It is proposed that 30 Minutes of Matter functions as a temporal and imagetic counter-narrative, offering alternative forms of representing and inhabiting memory-images within today’s accelerated present.
