Shooting in Shutter Priority Mode, I used a slow shutter speed to achieve a motion blur of the pinwheel. This shutter speed was slow so that the pinwheel would turn while the shutter was open. In order to get the correct exposure, the aperture had to be smaller to allow light to come in. The aperture at f/20 allows the background to be in focus.

Shooting is Shutter Priority Mode, I was able to use a fast shutter speed to freeze the pinwheel's motion. My shutter speed was 1/1000 of a second which means it was open for a very small amount of time. The camera automatically adjusted the aperture to f/4 to allow for enough light to come in so the photograph had good exposure. The aperture at f/4 creates a shallow depth of field and therefore the background is blurry.

This image was taken using ISO 25600 which is an exceptionally high film speed. This film is very sensitive to light and can be used in very low light situations to capture an image. The problem with fast film speeds is that the image have a lot of grain and are therefore very "noisy."

This image was taken using ISO 100. This is a slow film which means it is not very sensitive to light. It requires maximum amount of light to make a good exposure. Slow film is less grainy, but has less visual information.
