ISO questions
1. What are the three parts of the exposure triangle?
Shutter speed, ISO, and aperture
2. How much more exposure is there as you change from one ISO setting to the next?
When you make the ISO higher it allows for more light to come in. Making the ISO higher in darker situations helps with the lighting.
3. What is the main drawback to changing the ISO from low to high?
When the ISO is increased it can cause speckles in the background because you don't notice it.
4. What are a few ways to reduce the appearance of noise in the photo?
To keep the noise low in the photo keep the ISO low. The lower the ISO the lower signal to noise ratio (lots of signal, not much noise)
5. What is the difference between Chromatic and Luminance noise?
Chromatic noise is multicolored speckling where neighboring pixels show random color variations. Luminance noise is caused between random variations of brightness between neighboring pixels.
6. What are a couple of example of when and why you might want to increase the ISO of the camera?
If you're in a dark situation like a night shooting that's when you'll want to increase the ISO because it makes the camera more sensitive to light allowing for the picture to be more sharp.
