How is One Hour Photo established as a thriller (silent watch) - opening two minutes only.

In the opening credits of One Hour Photo the font is bright and bold with semi-continuous flashes. this is used by director Mark Romanek to show that a simple thing like photos being processed which will prove to be the main story line of how the film progresses can have physiological assets. I first watched this film opening in silence to analyse in more detail the other things in the shot. when the title 'One Hour Photo' comes onto the screen there are 3 pounding flashes which can represent the illusion the flashes cause and the quick blinking what the reader then does. it can also relate to a heartbeat and a increase in tension. in the first establishing shot we see a camera. typically with a red button to represent danger but also now the realization that along with the title the topic of cameras is likely to play a forefront in the plot. coming down in shutters to aid tension build up a man appears who we appear to be posing for a prison admittance picture. this in turn is introducing us to Robin Williams (the main antagonist) and forebodes what is going to happen once the film starts. The shot then cuts to a camera watching Robin Williams and a double sided mirror looking through to the room he is in. this therefore enforces the realization that he is under high security and he is a dangerous person to the outside world.
