In tennis, one is often asked to ‘hit through’ the tennis ball, not at it, just as a punter in rugby is supposed to kick through the ball to get the height he desires. This is, to my mind, fairly similar to the way I shoot with a rangefinder – I shoot through the moment, rather than at it.
What do I mean by this? Well, have you ever tried to capture a single moment (e.g. the point when a skateboarder goes airborne and reaches the peak of his trajectory) and found the darkening of the viewfinder on an SLR frustrating? With a rangefinder, you can see the whole moment happen, and rather than predicting the climax, you can observe it. I think this is a key to capturing the so-called (and cliched) decisive moment. And trust me when I say it feels just as good as a perfectly-timed tennis swing-through!
