If you were going to draw yourself running, skiing, or sliding, how would you show motion? What hints could you give a viewer of your painting that your subjects were moving? Observe Eadweard Muybridge's photography and/or slow down a video so you can look at individual frames. Notice the small, but consistent, changes that occur from one frame to the next. How does the human eye see these continuous frames as a moving picture? Notice the blurring of detail in quickly moving objects when you speed up the images.
