In 1983 Guido Guidi made a short series of photographs inside a single room in Preganziol, a small town on the plain between Treviso and the Venetian lagoon. Sixteen images, all of them taken within four bare walls. The only light came through two windows set crosswise to one another, so the room’s illumination shifted as the hours passed. MACK published the sequence in 2013 as a large-format hardcover: 28 by 39 centimetres, forty pages, sixteen colour plates.

At a glance the series reads as a photographer’s exercise — an inquiry into how light defines volume and how a photograph might describe physical space. Stay with it and the terms widen. A photographed room becomes a camera obscura; a window looking outward becomes an Albertian frame; bare walls carry an air of emptiness and abandonment; and the slow crawl of light across plaster measures time rather than space.

The sequence belongs to a preoccupation that runs through Guidi’s work: the void, and the knowledge that reality continues beyond the frame, unmeasured and unmeasurable. Photographing a corner of the Veneto in this way places him nearer to certain conceptual and architectural traditions than to documentary reportage, and the quality of the printing and the pacing of the plates are part of the argument rather than decoration.

Guidi was born in Cesena in 1941 and studied in Venice at the University Institute of Architecture, now IUAV, attending courses given by Bruno Zevi, Carlo Scarpa and Mario De Luigi, and later an advanced course in industrial design with Italo Zannier and Luigi Veronesi. He has worked as a photographer in IUAV’s Department of City Planning since 1970, and has taught at the Ravenna Academy of Fine Arts since 1989 and at IUAV since 2001.

For a collector, the relevant facts are few and specific. The edition was limited to 1,000 signed and numbered copies, and the format gives the sixteen plates something close to wall scale. It is a small, tightly argued book by a photographer who has thought steadily about space, light and the edges of the frame for five decades.
