A pretty sweet example of time in photography would be:

Eadweard Muybridge.

He's the bomb. Don't believe me? He was anenglish pioneer in capturing motion in photography. He created the zoopraxiscope which created moving images. for real. An interesting technique he would do is is capture the body in multiple positions on a single page. pretty sweet huh? He would do this by having the figure in a completely dark background. With the shutter open he would shine a light on the subject and click it on and off as the body moved, thus capturing the full movement. The dude has skills.

Here's some fun trivia about the man, the myth, the legend.
In 1887 he discovered his wife had a lover. So what did he do? He shot them man, right after he said "Good evening, Major, my name is Muybridge and here is the answer to the letter you sent my wife" ....Ok maybe that was over reacting...but eh i mean,..ok I cant really defend that.
