For this exercise I used a spinning bike wheel.
First exposure 1 sec everything is blurred and too much light has entered the lens creating over exposure. The next two exposures were at 1/2 sec and then 1/3 second. Blur is still in evidence at 1/3 sec the light is OK.
The next three shots are at speed of 1/13 1/20, 1/100, there is not significant difference between them however the outer wheel is getting gradually sharper.
These three shots are at 1/250, 1/1000, 1/2500. The images are still blurred in parts at 1/250 and 1/1000 at 1/2500 the picture is nearly still, only the fastest parts (the outer spokes show some blurring.
At the final shutter speed,1/4000 the picture is very shasp throughout.
