From 1962 to 1967, Blanchet filmed a series of 16-mm amateur shorts in a Parisian Ciné-Club while attending the screenings of Henri Langlois at the Cinémathèque Française.

Blanchet was inspired by Robert Flaherty, and the Direct Cinema tradition of Richard Leacock, D. A. Pennebaker, Michel Brault and Pierre Perrault.

He developed a series of microphones, built on new principles, and used them in his own films, generally mounted directly on a small video camera.

The sound is particularly transparent and the mikes produce an auditory "depth of field" that makes them particularly suited for one-person film crews.

[3] He also developed a series of serial microphones for acoustic instruments, and made sound recordings for e.g. Randy Weston, Richard Leacock & Sarah Caldwell, Jean-Louis Aubert and Alain Roudier.
