Aperture, Shutter Speed and ISO

Aperture
1. The part of the body that we can closely relate aperture is the eyes.
2. The smaller the Aperture the larger f-stop, the larger the Aperture the smaller the f-stop.
3. The Depth of Field is how sharp the background looks.

f2.8

f16

Shutter Speed

1. a.At the beginning while the sun was still up and the courtyard had reasonable good light you can use a slow shutter speed. 

b. At night when there is no sun and it has gotten dark you can use a long shutter speed to capture images.
2. Shutter Priority is when you manually set the camera's shutter speed and the camera picks the shutter speed depending on the amount of light in the lens. The camera will increase the lens aperture if there is too much light and vice versa if there isn't enough light.
Aperture Priority is when you manually set the lens aperture and the camera sets the shutter speed to show the image giving you full control over the depth of field.
Manual mode gives you full control of setting the aperture and the shutter speed.
ISO
1. The advantages of shooting with a higher ISO at a basketball game is it can quickly freeze and capture motion.
2. The author said to use a low iso when there is plenty of light unless the camera is mounted.
3. The author said to use a high iso when there is not enough light or you want to capture motion.
