"Obviousness is also the sign of a secret. The suggestion of an invisible presence arises when one looks at the walls that compose the second photographic opus by Adrien Boyer. But in a curious reversal, it is less what lies behind the wall than what it openly reveals that becomes an enigma. Obviousness is as mysterious on the side of the visible as it is on the side of the invisible; yet, to attempt to reveal this mystery, the wall—its "face" side—must express the disappearance of what once stood before it.", Michel Poivert
