My work is based on travels in different places of the world, in a personal photographic exploration that is not motivated by a specific subject. Rather than documenting, my purpose is to record scenes that may be used to question representation itself, to make appear different ways of reading pictures. I use both my own archive and the NASA's. Based on resemblances, their assembling is a mean to push this process forward, to reveal representation paradoxes implied by photography, and the way we comprehend them. Shown by two (or more), the pictures generate tensions, intervals, that lead to a different perception, to a new image, that blossoms in the mind. They deploy complex boundary-crossing systems — geographical, iconographic, or symbolic: from the inside to the outside, from wilderness to museums, from Earth to Mars, from a landscape to a flag.
