Shutter speeds

Thank you so much. I'm brand new to taking pics and it's taking me some time to grasp shutter speed. I spun the globe in each pic. 2 at 1 second and the sharpest shot at 1/60. The last pic at 1" I moved my hand while pressing the shutter button like you did in the video. Thanks again! Can't wait to see what I will learn from you next.
