Shooting in shutter prioritymode i used a slow shutter speed to achieve a motion blue 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 allow light
shooting in shutter priority mode i was able to use a fast shutter speed to freeze the pinwheels motion. My shutter speed was 1/1600 of a second which means it was open for a very small amount of time .The camera automatically adjusted the aperture to f/2.8 even tho its at f/3.2 to allow for enough light to come in so the photograph had good exposure.
Shooting in aperture mode this image has a aperture of f 2.8 and a iso of 100 and its shooting in 1/4000 of a second and it froze the pinwheel and the image is very clear no grain at all.
