The camera makes the moment eternal, especially after the invention of the portable camera. Early cameras took pictures more like portraits, all elements are placed in advance first, and the advent of portable cameras made it easy to take shots. But what is the meaning of recording moments, is it a record of emotions, memories, or events? Photography can stop time, and this frozen moment can be widely disseminated through the media, which is another influence of the media on the moment. That is why how the moment is captured on film has become a crucial proposition in the history of photography.

And when we talk about capturing the moment, the decisive moment is a theory that is inevitably too discussed in the history of photography. According to Henri Cartier-Bresson, the moment of shooting was decided before pressing the shutter, but now the moment of shorting is decided after pressing the shutter. This makes me wonder, now that modern reality capturing equipment has made great progress. The power of the moment is the picture itself or the story itself?

In this video I reproduced Bresson's 'Behind the Gare Saint-Lazare' through the iPhone, the most common reality capture tool nowadays. By documenting the whole process, I provoked a reflection on what is the decisive moment.
