Man With A Movie Camera (EOTWS)

End Of The Week Shorts #46 extract: Man With A Movie Camera (1973)

Crosswaite's Man With A Movie Camera is a Structuralist film that questions the function of focus and reflection in cinema. 

By racking focusing before and beyond a mirror that reflects the camera recording, this bears a strange illusion, one that has you ponder upon the role that depth-of-field plays in manipulating a three-dimensional space. The mirror itself extends the basic space of a room and the focus shortens it. Looking into the mirror through shallow focus has the reflection feel like a visual worm-hole of sorts. Maybe this is a study in mise-en-abyme too?
