Walking the Tight Rope
While not as impressive as crossing Niagra Falls, photographing children is in many ways the same kind of thrill.
You start with a goal that seems a long ways out.
The longer you are trying to reach the goal the more likely you will fail.... so fast is better.
Getting into a rhythm allows the session to move in the right direction.
Distractions are bad.
When bad things happen you have to trust your balance and experience.
Have a few tricks up your sleeve as a safety net to make sure you get the job finished.
