Exposure Principals

ISO 

ISO-  determines the sensor's sensitivity to light. When using the lowest ISO rating (100), you can see that the image will be darker than when using 400 or 600. When you set the rating to 6400 the image will be brighter. I set up the camera with a tripod to get the best results, and switched the ISO rating to get a picture of each rating. In the first picture you can see the difference between the green and the white SC letters when the ISO rating increases. The second picture shows all of the ISO ratings in one picture . 

Aperture- Controls the lens' diaphragm, which also controls the amount of light entering the lens. A larger aperture reduces the area of sharp focus and a smaller aperture expands the are of sharp focus. It is represented by the f number. I used a larger aperture to focus more on the checker pieces than the persons face.

Shutter Speed- The cameras shutter opens and closes to let light in. When shooting an action shot it is better to use a fast shutter speed because it freezes the movement. If I were to use a slower shutter speed , the image would have motion blur and we want to avoid that. In my picture I had the person move her head side to side and I was able to freeze the motion, focusing on her head.
