Aperture, Shutter Speed and ISO

 1. What part of the body should we closely relate aperture?

The eye (pupil).

2. Finish this sentence - the smaller the Aperture ______size_______, the higher the Aperture _______F-Number_________.

3. In your own words tell me how aperture impacts Depth of Field?

Smaller aperture size (f/16) results in a larger depth of field, and less background blur. Bigger aperture size (f/2) results in more background blur, and a shorter field of depth.

*big aperture size = brighter
*small aper. =darker





This photo most likely was taken with an aperture setting of F2.8, because the background is very blurred, creating a short depth of field.



This photo most likely was taken with an aperture setting of F16, because both the background and foreground are very sharp. You can clearly see the mountains in the back, as well as the plants in the front. 


Shutter Speed---------------






This photo was taken with a slow shutter speed, because the wind turbine's propellers look as if they're in motion and are blurred (motion blur).




This photo was taken with a fast shutter speed. Everything is sharp not blurred, and the image "freezes" the water splash in its position.

At the beginning while the sun was still up and the courtyard had reasonable good light

a.) a booth in the middle of the yard near the Tree
Slow shutter speed.
b.) a food booth outside under one of the big red awnings
Slow shutter speed.
c.) the Stars performance inside the gym
Fast shutter speed.
d.) students dancing near the center of the courtyard
Fast shutter speed.
e.) people streaming in from the front doors
Slow shutter speed.

f.) the basketball booth where students are shooting basketballs at a hoop
Fast shutter speed.

Towards the end when there is no sun and has gotten dark enough that you can't see from one end of the courtyard to the other.

a.) a booth in the middle of the yard near the Tree
Slow shutter speed.
b.) a food booth outside under one of the big red awnings
Slow shutter speed
c.) the Stars performance inside the gym
Fast shutter speed
d.) students dancing near the center of the courtyard
Slow shutter speed 
e.) people streaming in from the front doors
Slow shutter speed
f.) the basketball booth where students are shooting basketballs at a hoop
Slow shutter speed. 


2. 
(S or Tv)
Shutter Priority Mode: can manually change shutter speed, but aperture is auto-picked.
(M)
Manual: can change shutter speed, but can also change aperture
(P)
Program: auto shutter speed and auto aperture, aimed to shoot quick shots (freezing motion).

ISO---

-

ISO 200 was most likely used. The brightness is not very high, so the picture is dark, but has less noise.

Possible ISO 1600. Image is brightened enough where the building can be seen in night.



ISO 3200 on the right. Notice how "grainy" the image is compared to ISO 100, due to increasing brightness at an already mid-bright scene.

1. What are the advantages of shoot at a higher ISO at a sporting event like basketball or a night football game?
Photo will not be so dark, you will be able to see the event better.
2. What suggestions did the author make about using a low ISO?
Try to use it more if scene is not severely dark.
3. What suggestions did the author make about using a high ISO?
Don't use it so often, unless it is needed.
