Blur

This is a vertical pan. Find a clean area of forest with nice sized vertical trees and do a slow shutter with large DOF, pivot the camera at the wrist up and down with clean fast vertical motions as you release the shutter over and over. Seems simple but it's really hard to get just the right clean vertical blur with just the right contrast, lighting, no bright sky popping in on top. Taken in Smokey Mountains, Canon 5dMiii 1/4 sec F16 58mm
