A different example of using fast shutter speed to stop action. This was taken from inside a small plane on a scenic flight over one of New Zealand's famous National Parks. The challenge was to freeze the photo while the plane was moving.
@chejja This may not be what you had in mind for the challenge but it was a shutter speed challenge as the plane was moving and at times swinging and swaying!. Aoraki Mount Cook is New Zealand's highest mountain.
