Shutter speed to capture movement of a walker?

I can try this at home once I get off work, but just wondering what shutter speed will capture some movement in a fast paced walker?

1/15? 1/30? 1/45?

Distance from camera? Speed of walker? But the math is pretty simple.

Walker is about 3 MPH or about 4.4 feet a second.
At 1/15 of a second the walker will have moved 3.5 inches.

See, our teachers were right. We would have to do word problems when we get older.

Mrs. George would be so proud of me.

You've really got to expirment to see the level of movement you want. Anything from 1/60 sex to 5 sec

1/15 will usually do it, I can get safe shutter in 1/30 sometimes.

As has been mentioned, distance/focal length (or rather, the absolute size of the image on the sensor) matters. As well, the direction of movement also matters.

Movement across the camera requires a higher shutter speed than movement directly to or from the camera.

I've found, though, that 1/125 captures a walking person well enough in most situations.

4th grade. She really drilled math into me. She was ancient, a thousand years old. Funny thing is that when I had my son and we enrolled him in the same school, she was still there and still was ancient.
