Introduction
When you use TV mode on your camera it let you choose the shutter speed and then the camera chooses the aperture to achieve the proper exposure. This lets you be creative and also have control over motion blur. To freeze fast action you will need to set your camrea to have a high shutter speed. Then on the other hand to blur motion you have to set your camrea to a slower shutter speed.
What is Panning?

The picture above is a good example of panning. Panning is when you take a burst of picture focusing on the subject so that the background of your image is blurry. To get the best results start by chooseing a moderate shutter speed and then adjust based on subject speed. Then use continues focus/tracking AF mode so that way the subject stays in focus while you are panning. Make sure you are standing with both feet on the ground and only turning your torso. Then start trying different shutter speeds to find the best match for your subject.
When to use different shutter speeds?
A photographer should use slower shutter speeds when trying to achieve motion blur. Shutter speeds ranging from 1/30-1/80 of a second, and a good example of this is trying to photograph the wheels of a bike while someone is riding it. On the other hand a photographer should use faster shutter speeds when trying to freeze the motion of a photo. Shutter speeds for freezing motion should be 1/250 s or faster. An example of a way to freeze motion is by photographing a person walking.
Slow Shutter Speeds



These picture are a good example of short shutter speed, because as you can see the photo is burry. The first picture was a very slow shutter speed compared to the last one which was a much faster speed. The last picture could be used as a fast shutter speed but I just want to show the difference.
Fast Shutter Speeds



Here these picture shows faster shutter speed because it freezes the action that is taking place in the picture. The ball and also Jason are in foucus and nothing is blurry. The first two picture look like the exact same but they were taking at the same time.
Panning



These pictures are examples of panning because they show that the subject is not blurred, while the background is blurred. My subjects in these picture were Jason and Megan. Some good ways to make your photos better is to only turn your torso when photographing someone running.

This was Megan running in one of my panning picture. This was my favorite image because Megan was in full focus, while the background was perfectly burry. This picture also makes her look like she is running really fast which is cool.
