In the pictures, on the bottom right of each shot, you can see the digital background noise increasing with as the ISO increases. With the ISO increasing, the camera needs less light to form a picture with, and faster SS can be used.
1. What are the three parts of the exposure triangle?
-The parts pf the exposure triangle are the lens aperture, the shutter speed, and the ISO setting.
2. How much more exposure is there as you change from one ISO setting to the next?
- Half the exposure is needed because the ISO doubles the sensitivity of the camera.
3. What is the main drawback to changing the ISO from low to high?
- With higher ISO settings, you receive more digital background noise.
4. What are a few ways to reduce the appearance of noise in the photo?
- You can use build in settings on the camera and there also ways to decrease noise with editing software.
5. What is the difference between Chromatic and Luminance noise?
- Chromatic noise causes neighboring pixels to to show random colors. Luminance noise causes pixel light variables to change.
6. What are a couple of example of when and why you might want to increase the ISO of the camera?
- Snapshots after dark or if you need to take a stop action in low lighting.
