Using a single-lens reflex camera with a high speed trigger opens new doors in photography.
The human eye isn't fast enough to catch all of the beauty in life. When a balloon pops, for example, we blink. When a glass shatters, we cover our eyes. Neither of these things evoke beauty or awe in most minds, but that's because most of us haven't seen it through the lens of a high speed camera capture. Even your camera is too slow to capture the instant a balloon pops or a glass shatters. But with a high speed trigger, your camera can be rigged to capture both of these instances, and more, in all of their magnificent glory.
