Quérel considers the cinema projector as an instrument. Applying his experience in improvisation, he has developed specific techniques and ingenious manipulations allowing him to play with the spontaneity of a musician. He plays with "La Cellule d'intervention METAMKINE", film/music performance based on improvisation, with Jérome Noetinger and Christophe Auger. He co-founded "L'Atelier MTK", a collective ‘handcraft’ cinema laboratory. Taking part in a performance of expanded cinema means giving oneself up to the synaesthetic experience, setting aside the traditional rules of film language and developing a receptive attitude, free of critical criteria... Light is the starting agent of this chain reaction, the projector its tool.
