A. STOPPING MOTION This is the easy one.
We stop motion by using a fast
shutter speed. speed should be at least equal to the size of your lens.
Example: 50 mm lens use 1/50 of a second to stop motion. 200 mm lens
use 1/200 of a second.
This rule of thumb is why a wide angle lens is better for stopping motion
of trees and flowers on a windy day. If you want to get the blur of the
trees as the branches move, a telephoto lens with the longest possible exposure
is what you want.
To maintain sharpness, use the lowest ISO that allows you to shoot at the speed
you want to shoot.
If objects are moving extremely fast, you may have to make your shutter speed
faster and therefore have to increase the ISO.
Be sure to consider the depth of field you want in your image and set your
B. CREATING BLUR
1. Blurring the moving object. This is the
ball rolling down a hill or motorcycle going down a street or a waterfall.)
Figure out where you want
to photograph the moving object. Be sure to look at your background to get
the effect you want to create. Do you want the motorcycle passing trees in
a forest or buildings or something else. Put you camera on a tripod and
use a remote release. By doing this you can see your subject coming and
anticipate the time it will be where you want it. If you have continuous
shooting, start shooting a little early and continue until the subject is past.
You will shoot a lot more images but greatly increase the likely hood of getting
what you want.

the aperture that gives you the greatest depth of field
a neutral density filter.
Tip: Use a
longer lens. It will blur at more easily. It magnifies the
image and the motion.
C. BLURRING THE BACKGROUND. (This is the hardest). Used
mostly in sports.
You must pan with the
with you feet apart facing the background where you want to photograph the
subject. Twist your body to look where the subject will be coming
from. Practice the movement of the expected path. Try to match the
expected speed of your subject. If you can, follow several subjects doing
the path to get the feel of the movement. Now follow the subject and click
as it passes your predetermined point. Be sure to follow through with your
panning movement until after you release the shutter. This is the opposite
of what we train for so it is very difficult. Also, you must stay exactly
with the subject in the in the same place in the frame. The slower your
subject moves, the longer the exposure must be.
Because you are blurring the background, depth of field is not critical. A
shallow depth of field may even be helpful.
are using a heavy lens, place your camera on a tripod with a ball head.
Loosen the ball head so it will swivel as you track your subject. Be sure
to check to see if you need to take a step.
