Aperture, Shutter Speed and ISO

APERTURE


1. Aperture in the camera is like our pupils, deciding what amount of light to let in. If there is too much light, the background can be blurry.
2. The smaller the Aperture number, the higher the Aperture size will be.
3. If there is a smaller aperture, which lets more light in, and there's already enough light, then the background will be more blurry and not as "good." The Depth of Field is not just the focus of the picture, but everything in it.

ISO

1. An advantage of using a higher ISO during a sporting event is that it will come out better, there won't be as much motion blur because if the ISO is higher than the base, the speed will be a fraction of a a second instead of a second or more.

2. The author said that if someone is using a lower ISO, than the picture won't add more "noise" to it. They also basically said that lower ISO is more for when things aren't moving as fast, or not at all.

3. The author said that using a higher ISO is more for when the object is moving at a faster speed and a second would be too long and create motion blur. When theres a fraction of a second needed to take the picture the ISO needs to be higher.
