Blow-Up

BLOW-UP is NOT "about the possible dehumanizing effects of photography..." but rather a movie version of the philosophical question: "If a tree falls in the forest and no one hears it, does it make a sound?"

In this case, if a murder is committed and there is no evidence, did it really happen?

While seemingly about a successful, but hedonistically superficial, photographer who films both wartime brutalities and fashion, Thomas (David Hemmings) comes to finally realize that his images only create an illusion of the real world.

He discovers that he has accidentally photographed a murder when he develops and enlarges ("blows up") the images of photographs taken of a couple in an otherwise deserted park. He even returns to the scene and finds the victim's body. But when the photographs AND the negatives AND the body disappears AND there is no report of a missing person, he discovers that he has no evidence of a murder having occurred.

In the end, when he throws back the imaginary tennis ball to the pantomime players on the tennis court, he realizes that what he accepts as reality is really only an illusion.
