Sometimes it's difficult to find an angle and sometimes it's difficult to capture that pivitol moment. Documentary photography is so much more of a challenge then all the other types of logistical photography. The only thing you can really control is your ability to stick with the shot because the situation is completely dynamic. You can't just stop everything and direct what's happening when you are the quiet "bird" from above. These kind of shots are my favorite to take because I know I have to be patient and wait for something to happen.
