Introduction
Shutter speed is a great mechanic to learn how to use because it can make the image appear different in ways that may pull the viewer into the picture. A faster shutter speed can make an image seem frozen while a slower shutter speed can make the image look like it’s in motion.
Panning is what photographers do to get many pictures from a scene instead of just one or making a moving subject clear instead of blurry. What they do is they move the camera at the same speed as an object that is moving to keep it sharp.
A photographer should use a short shutter speed when wanting to freeze a moving subject. (Humans/animals)
A photographer should use a fast shutter speed when wanting to capture an image of a still subject. (Water or landscape)
Short Shutter Speed Examples:


These pictures both show slow shutter speeds because it freezes the motion in both pictures
Long Shutter Speed Examples:


Both of these pictures demonstrate a long shutter speed because the ball is blurry in both pictures. This shows that the ball has movement.
Panning Examples:


These images both use panning by blurring the background while keeping a clear subject
