Patience is the key
From my first forays into the world of photography, I struggled a lot with patience. At each stage of my photography, I had to practice my patience --in terms of how much time to invest in a single photo or scene.
Some pictures freeze a perfect moment that, by nature, is absolutely unrepeatable. And they are treasured because there is no chance that everything will look the same again because everything happened spontaneously at that specific moment. Think for a second about a bird that flies near the frame of the side window of your car. The action lasts a fraction of a second, ends, and does not repeat. Right?
But there are times, when the situation is not like a flying bird, because of the events last several seconds or even minutes (like a President speech, or the first dance). Perfect, in this cases, we have to use at our advantage the exercise of our patience: I mean, working on a better composition and better overall frame, but also capture the more "decisive moment" as possible. That's why patience here is the key.
