Panning requires a steady hand and a relatively slow shutter speed.
The actual shutter speed depends on the speed of the subject but generally it will be 1/200th or slower. 1/200th if your subject is really flying along, like a speeding car on a race track, and maybe as slow as 1/40th of a second if your subject is a runner on a track.
2. Keep in mind that the faster your shutter speed is the easier it will be to keep your subject crisp.
Especially as you’re learning the art of panning, don’t slow your shutter down too much. Just keep it slow enough to begin to show some motion. As your confidence increases and you’ve got the hang of things, go ahead and slow your shutter more and more to show even further pronounced motion and thus separation of your speeding subject from the background.
3. Make sure your subject remains in the same portion of the frame during the entire exposure: this will ensure a crisp, sharp subject.
4. Remember that the faster your subject is moving the more difficult it will be to pan.
This point goes right along with number 3. It’s harder to keep your subject in the same portion of the frame if it’s moving faster than you are able to. So again, start with something a little slower and then progress from there.
