One of the fundamental tools that a photographer has at his/her disposal is the ability to record time. This isn’t just the moment in time, or the ‘decisive moment’, as Cartier-Bresson called it, but the duration of the time interval as well. It’s a matter of when and how long.
We can not only get the sense that we are witnessing a precise moment in history but there is a passage of time, an event taking place that requires of the viewer, an understanding of progression; moving from one place to another, moving forward in time and space. Time and movement in photography are synonymous.
Modern cameras have the technology to record smaller and smaller time intervals. It is quite feasible that your camera could be capable of recording 1/6000th second or less and with a strobe light, 1/100 000th second is possible.
This capability allows us to capture and freeze motion and to recall that moment over and over again. We are also able to capture progression by photographing in quick succession by using sequence shooting with the camera or repeat lighting with a flash. A sense of motion and passing time can be presented in many interesting ways. By slowing down the shutter speed, any moving object will be blurred. Although we might try to avoid this, it also has the effect of establishing a sense of motion (and hence the progression of time) in the photograph.
