Today we are going to learn about all three and how they impact our photography.
Let's start with Aperture as it is probably the hardest of the three to full understand.
Directions:
Go to this website and read about Aperture:
READ AND POST EXAMPLES: Once you are done reading - I want you to use google and find me an example of a photo taken at aperture setting F2.8 and an example of a photo taken at F16 or higher. DO NOT USE the photos on the website I sent you to, find different ones. Post those photos on your blog and label them.
ANSWER: Then answer the following questions:
1. What part of the body should we closely relate aperture?
2. Finish this sentence - the smaller the Aperture _____________, the higher the Aperture ________________.
3. In your own words tell me how aperture impacts Depth of Field?
Now lets move on to Shutter Speed. This is a little easier to understand but we should read about it here:
READ AND POST EXAMPLES: Once you are finished reading about Shutter Speed, I want you to use google and find me an example of a photo taken with a high shutter speed and one taken at a slow shutter speed (you do not have to show blur unless you want but I still need to see an example of a photo that COULD have been taken at a slow shutter speed). Post them both on your blog and label them.
Then answer the following questions:
Do: 1. If you were assigned to shoot at Blue and Gold night, which was earlier this month, what shutter speeds (slow, medium, fast) 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 wall
- d.) 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 it is dark so there is not enough light to 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 circle
- f.) 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.
Now for the last of the pillars, ISO. Lets go read some more at this website:
READ AND POST EXAMPLES: Once you are finished reading, 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.
Then answer the following questions:
1. What are the advantages of shooting with a higher ISO setting at a sporting event like a night football game?
2. What suggestions did the author make about using a low ISO?
3. What suggestions did the author make about using a high ISO?
Practice: Now that we have a basic understanding of the three pillars, let's look at some direct examples of what happens in when you change Aperture and Shutter Speed. Go to the following website:
I would like you to experiment with all the settings so go through them step by step. Start with F2.8 and see what happens at each shutter speed, repeat for all of the Aperture settings at each stop on the Shutter Speed table.
On your blog list the exposure that looks best to you for EACH F-stop. I will help you with the first one here: F2.8 - looks the best at 1/125th of a second shutter speed.
Do: Now its your turn - tell me which ones look the best for:
- F4
- F5.6
- F8
- F11
- F16
- F22
Also please tell me what is happening with the backgrounds at each F-stop. Again here is the first answer:
EXAMPLE: At F2.8 there is no background visible - it is very blurry and all you can really see is the couple.
Now its your turn at each F-stop tell me what the background looks like. Is it in focus or blurry?
Finally, what is happening to the subject (the people) at SLOW Shutter Speeds? What could the photographer do to help combat this problem?
What is the lowest Shutter Speed do you think a photographer can hand-hold the camera without a tripod?
What is the lowest Shutter Speed do you think a photographer can hand-hold the camera without a tripod?
If you want to see more of this - try this website - I like its exposure simulator too:
If you are brave - you should try clicking the manual button in the middle of the control panel. You will be shooting in manual next shoot......be ready!!!!
Now to our last stop today:
I want you to take the two tests. One is called "Image Sorter - Depth of Field." The other is called "Image Sorter - Shutter Speed and Motion."
How well did you do? Do you understand Aperture, Shutter Speed, and ISO better now?
