How many visits to the same spot does it take to distill a shot from something that doesn't quite work to something that far exceeds your expectations? In my case with this location, at least 20.
I have in my library the 20+ shots to prove that it pays to be persistent. So what was the difference this time you might ask. The difference was shifting the focus from the falls to the tree branch.
In all of my previous shots, I tried to make the falls the subject. When I made the tree the subject, this shot finally fell into place. It pays to be persistent.
