Aperture, Shutter Speed, and ISO

Aperture

1. We can closely relate aperture to the human eye.

2. The smaller the aperture number, the higher the aperture size.

3. Aperture affects the depth of field in a shot because it controls what the picture is focused on.

• You can shoot in aperture priority mode and the camera automatically sets the shutter speed. You can set the camera to shutter priority mode and you choose the shutter speed, but the camera will set the aperture for you. If you choose manual mode, you choose the aperture and the shutter speed.

ISO

1. Advantages of shooting at a higher ISO when shooting at a basketball game or a night football game is that in these situations, there isn't very much light available and you don't want the pictures to show up dark. A higher ISO will make the picture lighter.

2. The author suggests to try and use lower ISOs whenever possible. He says that whenever you do, give your camera enough time to take the picture and that moving subjects will end up looking like ghosts.

3. The author suggests using higher ISOs whenever the picture does not have enough light. Also he suggests using a higher one whenever you're capturing an ultra-fast subject.
