Blow Up is not a "fun" film to watch, but it is fascinating. A photographer shoots pictures in the park, thinks he's stumbled on a romantic moment between two lovers in one of his pictures, but as he enlarges it over and over he begins to be convinced he's caught a murder on film. The genius of Antonioni's film is how he acknowledges the faults and manipulative capability of the photographic medium - it reflects reality, but is it real? It's the central dilemma of the entire film, and its images only generate hypotheses instead of facts. It's an unsolved mystery, but one that the audience must sort out not through the film's very bare plot, but in how they think (or to what degree) photographs can capture truth - what is truth? what is realism? is it a movement or a conundrum?
