Aperture, Shutter Speed, ISO

Aperture

This photo would be most likely taken at F2.8.


This photo can easily be taken at F16.

Then answer the following questions:

1. What part of the body should we closely relate aperture?
Our eyes, the pupil.
2. Finish this sentence - the smaller the Aperture ______the bigger the F-Stop (and the blurrier the background)_______, the higher the Aperture ____the smaller the F-Stop (the clearer the background)____________.
3. In your own words tell me how aperture impacts Depth of Field?

Aperture controls how much depth is in a photo. A small aperture can take sharp photos of landscapes, showing a large depth of field, and a big aperture will take clear photos of close subjects, resulting in a small (shallow) depth of field.

 Shutter Speed

Low Shutter Speed Photo (the car lights blur).


High Shutter Speed (water is "frozen in time")

Then answer the following questions:

1. If you were assigned to shoot at Bulldogs and Hotdogs night, which was a few weeks ago, what shutter speeds do you think you would have to shoot at the following events that night I would like you to answer the question for the following two situations:

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
Normal to high shutter speed (if tree moves)
b.) a food booth outside under one of the big red awnings
Slow Shutter speed
c.) the Stars performance inside the gym
High Shutter Speed
d.) students dancing near the center of the courtyard
High Shutter Speede.) people streaming in from the front doors
High Shutter Speed
f.) the basketball booth where students are shooting basketballs at a hoop
High shutter speed (unless the booth is in poor lighting-then normal 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
High Shutter speed (artificial lighting)
d.) students dancing near the center of the courtyard
Normal to Slow Shutter speed (increase ISO maybe?)
e.) people streaming in from the front doors
Normal to slow shutter speed
f.) the basketball booth where students are shooting basketballs at a hoop

High shutter speed? (unless it's in the courtyard --> slow shutter speed)

2. List the three settings your camera has regarding setting shutter speed (these are found at #5 on the Shutter Speed website. Explain how each works - DO NOT COPY AND PASTE, use your own words.

Manual- control the Shutter speed manually (along with other aspects)

Shutter-Priority- everything except Shutter speed is automatic; user can manipulate shutter speed.

Program- everything including shutter speed is automatic

ISO

http://mansurovs.com/what-is-iso-in-photography

Once you are finished, please go to google and find me an example of a photo taken at ISO 200 and a photo taken at ISO 3200 or 6400. Post both on your blog and label them.


ISO 200 photo- no grain, meant to be dark.



A close up of a photo in ISO6400 - very grainy

Then answer the following questions:

1. What are the advantages of shoot at a higher ISO at a sporting event like basketball or a night football game?

You are relieved from taking the photos with low shutter speed; you can take high shutter speed photos without any exposure problems.
2. What suggestions did the author make about using a low ISO?
Use it when there's plenty of light. Recommended is to use it while changing shutter speed or aperture if its safe.
3. What suggestions did the author make about using a high ISO?
Use it when you are fighting against motion blur and need light to counter the underexposure the high shutter speed will cause.

Now that we have a basic understanding of the three pillars, let's look at some direct examples of what happens in when you mess with Aperture, Shutter Speed and ISO. Go to the following website:

http://www.canonoutsideofauto.ca/play/

This simulates a DSLR camera. Make sure you set the camera on MANUAL setting at the top.

List the aperture settings available on this camera.
F2.8, F4, F5.6, F8, F11,F16, F22
List the shutter speed settings available on this camera.
1 sec - 1/4000 sec

List the ISO settings available on this camera.
ISO 100, 200, 400, 800, 1600, 3200,6400, 12800 25600.



Now have some fun and play with the settings. We will play with this site or one like it more later.
