Exploring ISO settings
1. What are the three parts of the exposure triangle?
2. How much more exposure is there as you change from one ISO setting to the next? 3. What is the main drawback to changing the ISO from low to high? 4. What are a few ways to reduce the appearance of noise in the photo? 5. What is the difference between Chromatic and Luminance noise? 6. What are a couple of example of when and why you might want to increase the ISO of the camera? |
1.The three parts of the exposure triangle are aperture, ISO, and shutter speed.
2. The ISO setting doubles each time and as it does this, the exposure is cut in half. 3. The main drawback when increasing ISO is that it adds noise to the photo. 4. In the camera settings there is a high ISO reduction setting that will help filter your high ISO photos. However, if you choose to turn this off and take raw photos, some Photoshop sites can help you reduce noise. 5. Chromatic noise is random spots of color that are usually relatively easy to correct. Luminance noise is the random variations of brightness between pixels and is harder to correct. 6.you can increase ISO in night time shots with a tripod, low light sports, or snapshots indoors after dark. |
