In this assignment, students learned about how shutter/aperture controls exposure. In terms of shutter-speed priority, students had to take photos of a certain action four times, each time changing the shutter-speed to show the difference between how to set up stop-action shots as opposed to motion-blurs. For aperture, students were told to take four photos of the same subject while experimenting with the f-stops to show a change in depth of field.
Shutter Speed Priority
Shutter Speed: 1/8
Shutter Speed: 1/20
Shutter Speed: 1/50
Shutter Speed: 1/80
Explanation: In the first photo, a low shutter-speed of 1/8 showed motion-blur, because the lower shutter-speed, the more light was being let into the camera, therefore showing the motion of the object. In the last photo, there's a faster shutter-speed of 1/80, showing the object more clear and "stopped-action," making the object seem like it has froze mid-movement because less light was being let into the camera.
Aperture
Explanation: In the first photo, there is a small f-stop number, a small depth of field, a greater aperture, and more light being let into the camera. In the last photo, there is a large f-stop number, a large depth of field, a small aperture, and less light being let into the camera.
Final Questions
1. A fast shutter does what to an image?
A fast shutter shows stop-action in the image.
2. A slower shutter-speed causes what effect on an image?
A slower shutter-speed causes motion-blur on an image.
3. A large aperture causes what effect on an image?
A large aperture causes a small depth of field.
4. A small aperture causes what effect on an image?
A small aperture causes a large depth of field.
A fast shutter shows stop-action in the image.
2. A slower shutter-speed causes what effect on an image?
A slower shutter-speed causes motion-blur on an image.
3. A large aperture causes what effect on an image?
A large aperture causes a small depth of field.
