Photography has been used to fix a state at a specific time. The man-made slow rupture by plants is then maintained in time. At the edge of breaking, the concrete shows sinuosity, and future roots growth. Those photographs reveal the plants’ strength, and the useless act of human being to control it. By displaying those work in event like exhibition, I oppose two temporalities : nature and atmosphere, slow, continuously, almost invisible ; and the one time events, fast.
