exf f. – days of experimental film frankfurt is an annual festival dedicated to experimental and avant-garde film in all its diversity, both historical and contemporary.
Offering no competition, exf f. is defined by a non-hierarchical understanding of filmmaking and film culture, aiming in particular to showcase film practices that focus on analogue film (be it Super 8, 16mm, 35mm or 70mm).

Microscope is very pleased to present Anthony McCall’s groundbreaking piece “Light Describing a Cone” (1973) as part of its series of imageless film performances and other works in connection and collaboration with the current series “Imageless Films” at Anthology Film Archives.

Part of a series of works collectively referred to as solid light films, Anthony McCall’s Line Describing a Cone sees the fog-thickened beam of a 16mm projector transformed into a three-dimensional moving sculpture. As the beam is viewed from various vantage points within the space it transforms, shifts, and demands attentive observation.
