I setup the camera watching the trees erratically swaying in the 50-70MPH winds from Tropical Storm Hannah.
There are no effects, straight from the camera, just a slow shutter speed to capture the movement.
There was no sun, only frantic clouds, and rain. The winds were getting up there when larger pines started to sway a bit.

These photos are mostly of some small white birch trees blowing in the wind.
The light green is the underside of the leaves.
