Aperture, shutter speed, and ISO

1. It is related to the  Pupil  . 
2. The smaller the Aperture number , The bigger the aperture opening .
3. The smaller the f-stop the more light enters and it focuses on both the foreground and background, the larger the f-stop the less light enters and the background is blurred out.
4. f-5.6, f-6.3,f-7.1, f-8.0, f-9.0 f-10, f-11, f-13,f-14, f-16, f-18,f-20, f-22, f-25, f-29, f-32,f-36
5. f-36, and f-5.6

A: Fast/ medium

B: medium/ slow

C: medium/ slow

D: slow/ slow

E: slow/ slow

F: fast/ medium

 2. The lens aperture, and the shutter.

• With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash.


• When there is plenty of light, you should always use the lowest ISO, to retain the most detail and to have the highest image quality.
• Set the ISO higher when theres not enough light, and also to be able to freeze motion
• 100, 200, 400, 800,1600,3200,6200

f2.8- because the background is blurred out.

f 16- because the background isn't as blurred out.
