Aperture, Shutter Speed, and ISO

Aperture


Aperture setting F2.8


Aperture setting F16

1) Aperture could be compared to the pupils of our eyes.
2) The smaller the aperture, the more light is let in and the less depth there is. The bigger the aperture is, the less light is let in, and the more depth there is.
3) Aperture effects the depth of the field by blurring or not blurring out the background. Smaller aperture blurs more of the background and creates less depth. While larger apertures keep the background clear and create more depth. 

Shutter Speed


High Shutter Speed


Low Shutter Speed

1) a. High shutter speed
b. Medium shutter speed
c. Low or High shutter speed - It depends what type of photo one is trying to take
d. Low or High shutter speed
e. High shutter speed
f. Low shutter speed

a. Low shutter speed
b. Low shutter speed
c. Low or High shutter speed
d. Low shutter speed
e. Low shutter speed
f. Low shutter speed

2) The three shutter speeds are Fast, Slow, and Long. Fast shutter speed freezes action. Slow shutter speed can be used for normal photography and slow subjects. Long shutter speeds are used for darker settings or night photography.

ISO


ISO 200


ISO 6400

1) Shooting at a higher ISO can increase the brightness of a photo that you take at night or in a dark setting.
2) The author suggests that if there's enough light, you should always use the lowest ISO of your camera.
3) The author also says that the only situations where you should use high ISO is when your scene doesn't have enough light or when your subject is moving fast and you want to prevent blur.
