Aperture Mode
Long Depth of FieldThis image has an aperture of f/16. That means that it has a long focal length and a small aperture opening. I shot this on aperture priority mode so the camera adjusted the shutter speed to 1/60 which means 1/60 of a second of the time for exposure. This created a motion blur of the pinwheel because the shutter was open long enough for the pinwheel to spin. The larger focal range (smaller aperture hole) means the background is in focus.

Shallow Depth of fieldThis image has an aperture of f/2.8. That means that it has a shallow focal length and a large aperture opening. I shot this on aperture priority mode so the camera adjusted the shutter speed to 1/2000 which means 1/2000 of a second of the time for exposure. This is very fast and therefore allows the shutter to let in less light. This is why the pinwheel is frozen, because the shutter speed captured the image quickly. The smaller focal range (larger aperture hole) means the background is blurred because the aperture could only focus on a shallow depth of field.

Shutter Mode
Freeze MotionShooting in Shutter Priority Mode, I was able to use a fast shutter speed to freeze the pinwheel's motion. My shutter speed was 1/800 of a second which means it was open for a very small amount of time. The camera automatically adjusted the aperture to f/3.5 to allow enough light to come in so the photograph had some good exposure. The aperture of f/3.8 creates a shallow depth of field and therefore the background is blurry.

Motion BlurShooting in Shutter Priority Mode, I used a slow shutter speed to create a motion blur from the pinwheels motion. My shutter 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/11 allows the background to be in focus.

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

This image was taken using ISO 2500 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 images have a lot of grain and therefore very "noisy."
