Aperture, Shutter Speed, and ISO

f/2.8

f/16

We relate aperture with the human eye. 

The smaller the aperture, the larger the f-stop. The higher the aperture, the smaller the f-stop. 

The smaller the aperture, the more focused the background will be and vice versa.

Using a higher quality ISO in certain circumstances like these gives you the highest quality image.

The author recomends you use a low ISO whenever possible.

The author recomends to use a higher ISO when there is not enough light for the camera to be able to quickly capture an image.
