Just as you are ready to enter the house at Fallingwater by Frank Lloyd Wright in Bear Run, Pennsylvania, you cross a bridge that takes you over the water that makes the waterfall. You are not allowed to take photos inside the house or use a tripod so I handheld some shots of the swollen fast moving creek above the bridge. The water was actually generating a nice fog above it. The first view is a long exposure with low ISO to show the water movement and the second view is quick exposure.

Which is better? The are from the same position on the bridge.
This view shows the fog a little better:
