Exploring ISO Settings
1. What are the three parts of the exposure triangle? The three parts of the exposure triangle are the ISO, time shutter speed, and F-stop aperture.
2. How much more exposure is there as you change from one ISO setting to the next? When you change from one ISO to the next, the exposure doubles.
3. What is the main drawback to changing the ISO from low to high? The main drawback to changing the ISO from low to high is that a lower ISO creates a picture with better quality. The good part of having a higher ISO number would be that it is able to capture a moving object and be completely in focus.
4. What are a few ways to reduce the appearance of noise in the photo? A few ways to reduce the appearance of noise in the photo are by increasing the ISO if you are shooting in marginal conditions or if your DSLR has a full auto mode change it to full auto.
5. What is the difference between Chromatic and Luminance noise? The difference between Chromatic and Luminance noise is that chromatic has multicolored speckles, the pixels differ in color randomly and it is easy to reduce the noise without changing the image detail. While luminance is more difficult to deal with the noise reduction process because it is difficult to distinguish noise from real detail.
6. What are a couple of example of when and why you might want to increase the ISO of the camera? A couple of examples of when and why you might want to increase the ISO of the camera are if you are taking a picture of a moving object and to avoid camera shake.
