F22 and F3.5

F22

F3.5

1. Aperture is a device that controls the amount of light admitted.

2. Depth of field is the distance between the closest and farthest point in complete sharp/clear focus.

3. The change in speed when adjusting the aperture increases in speed when using F3.5 and decreases in speed when using F.22.

4.An aperture of F22 is a small aperture.

5.An aperture of F3.5 is a big aperture.

6.If shooting a group of people that are at different distances than you, you would shoot at a F22 aperture because you want to keep them all in focus so you need to let in less light.

7. If shooting a group of people but only wanting to keep the subject in focus you would shoot at a F3.5 because with that aperture it lets in more light.
