Assume you were given an assignment from a large advertisting company. "Take a shot of running" , well that doesn'r really explain much does it? You could have:
a running nose
running at dawn
running at sun set
Before accepting an assignment I assume that you'd want to know exactly who you're to photograph running and when.
I'm not sure to understand completely your comment. What do you mean ?
Thanks for looking
