Aperture, Shutter Speed and ISO- What do They Do?

Aperture

        1. What part of the body should we closely relate aperture?
The pupil is closely related to aperture because it controls how much light we receive.


        2. Finish this sentence - the smaller the Aperture _____________, the higher the        Aperture ________________.
The smaller the aperture, the less light is let in, the higher the aperture, the more light is let in.

        3. In your own words tell me how aperture impacts Depth of Field?
With a small aperture, the entire image is sharp and a deep sense of depth is created. With a large aperture comes a large amount of background blur.

Shutter Speed

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: 
  

Shooting near the start of the day when everything is well lit.        a.) a booth in the middle of the yard near the Tree
I would shoot with a low shutter speed so the leaves on the tree could come out a little blurry.   
        b.) a food booth outside under one of the big red awnings   I would shoot with high shutter speed because there would be people surrounding the booth.   
        c.) the Stars performance inside the gym    A high shutter speed would be suitable because the performers are in motion.   
        d.) students dancing near the center of the courtyard   I would need to shoot with a high shutter speed to capture the movements clearly.   
        e.) people streaming in from the front doors    Use a high shutter speed to caption motion crisply.
        f.) the basketball booth where students are shooting basketballs at a hoop         A high shutter speed is necessary in this scenario so the ball does not appear blurry.


[shooting] Towards the end [of the event] 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

Shoot with the lowest shutter speed to let in as much light as possible. Use a tripod.

        b.) a food booth outside under one of the big red awnings

Shoot with a low shutter speed to let in as much light as possible (this would be in the shade, so using a low shutter speed is vital).

        c.) the Stars performance inside the gym

The gym is well lit and indoors so the amount of light present in the photo will not be affected. Also, the people are moving.

        d.) students dancing near the center of the courtyard

Shoot with a high shutter speed and with the flash on.

   
        e.) people streaming in from the front doors

Use a high shutter speed.

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

Using a low shutter speed would make for an interesting image. Shoot with a tripod.

Name 3 settings your camera has, regarding shutter speed    exposure: the amount of light in a picture
   depth: the amount of dimension in a picture
   noise: sharpness/blur in a picture

ISO

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

Even if the game is outdoors at night, you can make the image brighter. Instead of changing the shutter speed to fix the exposure (which would make the picture blurry in this case), just change the ISO

2. What suggestions did the author make about using a low ISO?
Use the lowest ISO whenever possible. Use a tripod or have your camera still.

3. What suggestions did the author make about using a high ISO? Use a high ISO to avoid motion blur. Only increase the ISO when there is not enough light for the camera to capture a sharp, bright image.
