Henri Cartier-Bresson was a French photographer. He brought to light the idea of what he called the decisive moment, and his candid photography is amazing. Henri said in a fraction of a second, of the significance of an event as well as of a precise organization of forms which give that event its proper expression.
Timing is everything to photography! Being an architectural-street scene kind of guy this is not as important on a moment to moment basis, as it would to be say a wedding photographer. I time my photographs based on when would this building have the best lighting on it. Simple as this is, you have to be there when the time is right and you are there to capture it.
That time was usually when I did not want to be there either... Usually for me it was late at night, early in the morning, foggy, rainy, etc. But, It was the right time to be there for the shot. Take the time to study your subject.
Photographers call it working the subject, capture images from a variety of angles, distance, lighting. And, always shoot "loose" when covering your subject, you can always re-crop the image later if needed. You can't add back something off your frame. When covering a subject take the time to take a good photograph, don't just blast off some frames because you can.. Check your settings, aperture, crop and shoot several with different settings. With my subject buildings, I have time to shoot without being rushed so much. I really don't want people in my photographs. It dates the image what ever the people are wearing date the image. I took the image below "Sunday Morning" at 1:30am in the morning down by Jackson Square in front of the church. There were two people hanging out and right before walking away they huddled up under the street lamp and kissed.
And yes, I was there to capture it! Score!
BTW, when photographing anything set your camera to it highest image quality setting! These no reason not too! Memory is cheap.
