Vocabulary
1. What are the three parts of the exposure triangle?
lens aperture, shutter speed and ISO make up
2. How much more exposure is there as you change from one ISO setting to the next?
When you change each ISO setting, the exposure is doubled. Ex. 100-200, 200-400
3. What is the main drawback to changing the ISO from low to high?
The problem with this is that all digital images have some background noise. Usually, you don't see it because it's faint compared to the light falling on the sensor, but when you increase the ISO, you amplify it, and it shows up
as a kind of random speckling. The higher the ISO, the worse the noise.
4. What are a few ways to reduce the appearance of noise in the photo?
You can reduce noise through different online resources such as photoshop
5. What is the difference between Chromatic and Luminance noise?
Chromatic noise is a multicoloured speckling, where neighbouring pixels show random colour variations.Luminance noise is caused by random variations in brightness between pixels and it's harder to deal with because noise reduction processes can't readily distinguish noise from real detail.
6. What are a couple of examples of when and why you might want to increase the ISO of the camera?
When you want to change the shutter speed without changing the aperture, instead you could change the ISO. You may also want to increase the ISO is when you want to shot inn a darker setting such as a show.
