L A – Exposure Basics Q1
After reading the appropriate section in your prescribed textbook From Snapshots to Great Shots, please answer the following questions:
- Name all the functions / buttons on the front of your camera
- Name all the functions / buttons on the back of your camera
- Explain how you would set the correct ISO
- Explain how you would change the aperture
- Explain how you would change the shutter speed
To set the correct iso press the iso quick button on the top of the camera. Then the numbers arrive on the screen. Use one of the wheels on top of the camera to pick the right iso and then shoot.
Iso controls the brightness of your photo. It brightens or darkens your photo. When you increase the iso number on the camera, the picture becomes brighter. So it is a good tool to take pictures in the dark. But at the same time, this is at the expense of the clarity of the image. If you take a picture with too high an iso, the picture will contain a lot of noise and will be seen as unclear.
To set the aperture, the dail wheel must be in P, A or M mode. By scrolling the wheel at the top of the camera the aperture changes.
Aperture is a hole in your lens that lets light pass through. Here you determine how much light that enters the camera body. You can shrink or enlarge the size of the aperture.
To set shutter speed, the camera must be in mode M or S. Use the dail weel to set the right mode. Then use the rear wheel at the top of the camera to set the correct shutter speed.
Shutter speed is the length of time your camera shutter is open, exposing light into the camera sensor. It changes the brightness of your photo and makes a dramatic effect by either freezing action or blurring motion.
