MAYA DEREN
[1917 – 1961] (born Eleonora Derenkowska) Ukrainian-born American experimental filmmaker

 
The still photograph is concerned with the isolation of the moment. The moment is stayed, composed within a stable frame. Films are concerned with the way in which a moment passes and becomes the next. This metamorphosis cannot be composed within the frame, but only through frames, from one frame to the next. - Maya Deren
