[Leica] Looking for a French movie starring a M6

Hi All

Last year on Bravo, there was a French made movie about a 'vagabon'
photographer, who got into a romantic affair with
a married woman he met at a cafe, her husband a businessman, always
traveling so she's lonely. After the affair, it seemed
he fell into a parallel world where none of his friends knew him, like he
didn't exist! Only the woman he had the affair knew him!
The guy sold his Leica for funds cuz when he went to his apartment, the door
was locked and the landlord didn't know him! The husband suspects this guy.

Anyone have know the name of this movie?  Thanks
