The movie screen, the TV screen, and the computer screen have become part of our everyday experience - substitutes for the architectural window that frames a view, and for the frame around a painting. But only in the last two decades have multiple screens become familiar. Typically film and TV both display a single frame on a single screen, despite other possibilities. What does it mean to "frame" an idea or experience using the new digital technologies? How does it change our "perspective"? Anne Friedberg takes up these issues with extraordinary theoretical sophistication and an impressive knowledge of history.
