Aperture, Shutter Speed, & ISO

Aperture

   F16

  F2.8

1. Aperture is like our eyeballs. Our eyes can focus on what we want and defocus.  

2. The smaller the aperture F-number, the higher the aperture F-number.

3. A photo with a small aperture focuses on all objects in the photo including the background. While photos with large apertures only focus on a main object in front, causing the background to be blurry. 

Shutter Speed

High

Low

a) High shutter speed because the bright light and to capture students moving at the booth.

b) Low shutter speed because the lighting is dim under the awnings and not too much motion happens.

c) High shutter speed because the performances are super fast pace and full of quick motions.

d) High shutter speed because there is a lot of quick movement and brightness.

e) Low shutter speed because the blur of students streaming in would look very cool in my opinion.

f) High shutter speed because the ball will be moving through the air 

a) Low shutter speed because it's dim outside

b) Low shutter speed because it will be very dark under the awning and darkness requires low shutter speeds.

c) High shutter speed because the movement is very fast and the gym will be lit up.

d) High shutter speed because of the fast movement caused by the dancing.

e) Low shutter speed because the blur of students rushing in against the contrast of the dark sky will look visually appealing like the highway photo above. 

f) High shutter speed because even though its dark there is a fast motion you want to freeze with your camera.

2. Aperture Priority, Shutter Priority, Manual.

Aperture Priority- When you set the aperture but the camera sets the shutter speed

Shutter Priority- When you set the shutter speed but the camera sets the aperture.

Auto- When the camera sets both for you.

ISO

 ISO200

ISO6400 

1. When you use a high shutter speed at sporting events you are able to get a clear photo because it allows the photo to capture the speed and motion.

2. Use a low ISO whenever possible, but especially when there is plenty of light. 

3. Use a high ISO when there is dim lighting and also when you want to capture a very fast motion photo.
