CAMERA SIMULATOR
Long Focal LengthThis image has an aperture of f/14. That means 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 of a second of 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 that the background is in focus.
Shutter Priority Mode |
Shallow Depth of FieldShooting on aperture priority mode, my aperture is set to f/2.8 which means that my focal length is shallow, but the diaphragm hole is large, letting in a lot of light. My shutter speed was automatically set to 1/1600 of a second which is very fast and the shutter is not open for very long, letting in less light. That is why the pinwheel is almost frozen in motion, because the shutter speed captured the image quickly. The background is blurred because the aperture could only focus a shallow depth of field.

In FocusShooting in Shutter Priority Mode, I was able to use a fast shutter speed to freeze the pinwheel's motion. My shutter speed was 1/500 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 to allow for enough light to come in so the photograph had good exposure. The aperture of f/2.8 creates a shallow depth of field and therefore the background is blurry.
ISO/Film SpeedFilm speed: Slow vs Fast |
Motion BlurShooting in Shutter Priority mode, I used a slow shutter speed to achieve a motion blur of the pinwheel. The 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 more light to come in. The aperture of 1/10 allows the background to be in focus.

The image was taken using ISO 100. This is a slow film 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 has less visual information.
ISO: Low vs High |
The 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 images have a lot of grain and therefore very "noisy".
