Aperture, Shutter speed, ISO - how do they all work?

Aperture:
1. What part of the body should we closely relate aperture? The part of the body we should closely relate aperture with is our pupil
2. Finish this sentence - the smaller the Aperture ____the larger F-stop_________, the higher the Aperture _The larger the F-stop_______________.3. In your own words tell me how aperture impacts Depth of Field? aperture impacts depth of field by making the main subject sharp and the background blurry during a large f-stop and  the opposite  during a small f-stop.
4. With the camera near you - tell me the F stops available on the lens currently attached

Photo taken with aperture setting F2.8


Photo taken with aperture setting F16 or higher

Shutter speed:

example of a photo taking with high Shutter speed
example of a photo taking at slow shutter speed:



1. If you were assigned to shoot at Blue and Gold night, which will be next month, 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 is still partially up and the courtyard has reasonable light
a.) the dunking booth
b.) the food eating contest
c.) the rock climbing walld.) someone working at a booth
e.) the DJ/MC working at the middle of the circle
f.) the Diamonds performance.

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.) the dunking booth
b.) the food eating contest
c.) the rock climbing wall
d.) someone working at a booth
e.) the DJ/MC working at the middle of the circlef.) the Diamonds performance.

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.
One of the three settings regarding setting shutter speed is aperture priority witch is an automatic way for your camera to set the shutter speed for you however you set the aperture. An other setting is Shutter priority were the aperture is set for you and your shutter speed is set by you. The final of the three settings you camera has regarding setting shutter speed is manual  were the aperture and shutter speed are set by you and not automatic by the camera
3. With the camera near you, what are the shutter speeds available to you on that camera? You will have to turn the camera on to determine this - hopefully you can figure out what setting to put the camera on to determine the answer to this question. 



ISO

Photo taken at ISO 200


photo taken at ISO 3200 or 6400
1. What are the advantages of shoot at a higher ISO at a sporting event like basketball or a night football game? The advantages of shooting at a higher ISO at a sporting event or at night is because there is not enough light and at a higher ISO you can capture a motion with low light.
2. What suggestions did the author make about using a low ISO?  The author suggested that you use low ISO during good sources of light.
3. What suggestions did the author make about using a high ISO? The author suggested that when there is not a good source of light or a motion is being observed it is best to use high ISO.
4. At the camera near you, please tell me what ISO's are available on your camera?

Sim cam:
F2.8- looks the best at 1/125th of a second shutter speed.
F4-looks the best at 1/60th of a second shutter speed.
F5.6-looks best at 1/60th of a second shutter speed.
F8-looks the best at 1/30th of a second shutter speed.
F11-looks the best at 1/30th of a second shutter speed.
F16-looks the best at 1/15th of a second shutter speed.
F22-looks the best at 1/8th of a second shutter speed.

F2.8 the background is not visible , it is blurry and all that is visible is the couple.
F4 The background is still not visible, it is blurry and all that is visible is the couple.
F5.6 the background is still blurry but slightly visible.
F8 the background is still blurry.
F11the background is slightly more visible.
F16 the background is visible.
F22 the background is completely visible and the couple is still clear.
The couple are beginning to become more blurry in a higher Fstop were the background is visible.  the photographer can keep the shutter speed high to expose the light to the couple more. the lowest shutter speed the photographer can keep the camera in is 1/15th of a second shutter speed.

Camera Sim:
I did good on the depth field and better on the shutter speed and motion. Yes this did make me understand Aperture, Shutter speed, and ISO clearer.
