Paul Bertier likes to combine rigor and sensitivity, conceptual and manual work. Marked during a trip in Asia by the strong contrast between mass architecture and landscape, where the city appears as a fictional space, he examines urbanity and its implementation, its edges, its borders, Its horizons. To explore this imaginary, he builts ambivalent images. Spaces and structures he shows are always in balance, ready to change, disappear or collapse. He also searches this tension with plastic choices : between realism of lights and abstraction of surfaces, between sensation of spatiality and physicality of materials. He imagines his pictures both as tangible objects and projection spaces so that the viewer forms his own story in these unstable areas, in suspens.
