Starting in the early '70s, Gioli began experimenting with pinhole photography, making photographs with what he called "stenopeic" devices (from the Greek stenos opaios, or "narrow aperture").
His experiments with stenopeic cameras represent an extension of the artist's reflections on the aesthetic capacities and enabling technologies of photography and film, and his recent pinhole film Natura obscura (2013), with its diffuse images of red poppies in a windswept Italian countryside illuminated by the setting sun, demonstrates that the filmmaker's explorations of photographic media are far from over.
Gioli was introduced to what was left of the CCI group by fellow filmmaker Alfredo Leonardi, but by then, he has said, "everything had become politicized." While continuing to work in film, he also began experimenting with photography--making photographs with what he called "stenopeic
" devices (from the Greek stenos opaios, narrow aperture).
