ISO

ISO: 200

ISO: 1600

The first photo is much darker than the 2nd because of the ISO change. The lower the ISO the less the photo will be affected by the light.

Depth of Field

When I move away from the person in focus, the depth of field changed because being closer meant less depth of field while moving further is more depth of field. 

Depth of Field Aperture

f/18, 1/1600

f/36, 1/50

f/36, 1/160

When using a higher aperture the depth of field becomes darker. As you increase the aperture, the depth of field becomes more bigger. The shutter speed determines the quality of the picture. The slower the shutter speed the more blurry the photo will come out, the faster the more clearer it will be. 

Aperture Focal Points

f/10, 1/50

f/5.6, 1/60

f/3.8, 1/500

In the first photo, both subjects are in focus. in the second photo only Marielys was in focus, and in the last picture Joel was the one in focus. In the last photos, only one person is in focus because the f stop is small which results to a bigger aperture. Both Joel and Marielys are in focus in the first photo because the f stop is much higher than the other two.
