Aperture

This is a one day assignment. If you finish, let me know and I will give you something more to do.

Aperture is part of the exposure triangle. It is the measurement of the lens opening and controls how much light enters the lens and determines your depth of field.
It is expressed in f-stops. The higher the number, the smaller the opening so the less light. The lower the number, the larger the opening so more light gets in.

You are going to practice manipulating your depth of field with Aperture Priority mode on the cameras. Your final product should look something like this:

The first photo's aperture is F5, the last one is F32. As the aperture increases, the depth of field increases. This means the background becomes more clear/sharp as the aperture increases. You can look at the Clorox container or Interact banner to really show this.

Aperture Practice:

1. Choose 3 - 4 small objects that have some detail to be your subjects.
   
2. Arrange them in a diagonal line with about a foot between each one in a well lit place.
   
3. Set up your camera and tripod. Put the camera in Av mode.
   
4. Adjust your aperture to its lowest setting and focus on the object closest to the camera (if you are having trouble with this, let me know). Take a photo.
   
5. Turn your aperture up and take another photo. Repeat 4-6 times until your aperture is at its highest setting.
   
6. Post your photos in a blog post titled Aperture on your Assignments page in order of increasing aperture.
   

Answer the following questions in the same post:

1. What is aperture?
   
2. What role does it play in exposure?
   
3. When might you want a high aperture?
   
4. When might you want a lower aperture?
