François Tomasi exhibits his photographs at the cloister of the Psalette in Tours from 21 to 30 September 2018. Like Claude Monnet who at the time of Impressionism brought a new pictorial lighting of the Cathedral of Rouen, François Tomasi reveals the metaphors of the stones of the Saint Gatien cathedral. His photographs express what stones contain mysteries. He confides: "I tried to make visible what belongs to the invisible of the dream It is in the Saint-Gatien cathedral of Tours, on the stone being restored, that I discovered many forms With the help of the light, my companion of all moments, I was able to photograph the imaginary ". Indeed, under the eye of the seasoned photographer, the stones become objectified, become striking allegories. François Tomasi transfigures the stigmata of the stones into a poetic photographic language. He gives us the visual resonances of a material that encloses the eternity and memory of a sacred building.
