"The photographer in Blow Up, who is not a philosopher, wants to see things closer up. But it so happens that, by enlarging too far, the object itself decomposes and disappears. Hence there's a moment in which we grasp reality, but then the moment passes. This was in part of the meaning of Blow Up." - Michelangelo Antonioni.
At the core of Blow-Up (Michelangelo Antonioni - 1966), there is this picture of a couple taken by a fashion photographer in a park.
Successively blowing it up, we find out that there's something going on which was invisible at first sight: a crime was perpetrated before our very eyes. Evidence is the shape of a body lying behind a tree, which we can see with the photographer when blowing up the picture even more...
Well at least it looks like the shape of a body. Because we zoomed in the picture so much it now looks like a collection of dots, blurring our vision.
In fact it's not a photograph any more, it's become an abstract painting and, as such, subject to multiple interpretations.
The same question over and over again: can you trust your eyes?
