Aperture, Shutter Speed and ISO

F2.8 Aperture 

F16 Aperture 

   

 1. What part of the body should we closely relate aperture?

The human eye, and specifically the iris, because it controls the amount of light let into the eye. 

2. Finish this sentence - the smaller the Aperture the more light let in, the higher the Aperture the less light let in.

3. In your own words tell me how aperture impacts Depth of Field?

Aperture impacts depth of field because the lower the aperture, the more depth of field you are going to get because it blurs out the background only focusing on you subject point. But if your aperture is high, both the background and the subject point will be focused.

Three settings regarding the shutter speed 

"Aperture Priority" - you are setting the aperture yourself, while the camera is setting the shutter speed for you 

"Shutter Priority" - you are setting the shutter speed, while the camera is setting the aperture for you

"Manual" - you are setting both the aperture and the shutter speed on your own

ISO 3200

ISO 200 

     

1. What are the advantages of shoot at a higher ISO at a sporting event like basketball or a night football game? 

The advantages are that when you use a high ISO you can get fast movement shots and still have them to be clear. When you are shooting at night a high ISO is important because it still captures a clear image in a low light setting. 

2. What suggestions did the author make about using a low ISO?

You should use low ISO when there is already a lot of light present, so you can get a clear photograph. 

3. What suggestions did the author make about using a high ISO?

You should increase your ISO when there is not enough light for the camera to be able to take the photo quickly.
