Exposure Triangle

Today you will add to your visual journal sequences of photographs showing your work and understanding of the exposure triangle. If you weren’t here on a day the class went out to shoot pictures, or need to re-shoot a sequence you may check out a camera. All students will take an Exposure Triangle Post-Assessment tomorrow.

A sequence looks something like this:

Shutter speed – Which shutter speed is best at stopping movement?

Aperture – Which aperture setting provides the most depth of field?

aperture-sequence-2

ISO – Which ISO has the least amount of image noise?

All links are due by the end of class today at the Google classroom assignment Exposure Triangle.

Exposure Triangle – ISO

Questions: Describe how you format an SD card using our DSLR cameras? What does AWB mean?

Learning Target:

  • I can adjust the ISO control of a DSLR camera and make five photographs using five different ISO settings.
  • I can post my pictures to my visual journal and reflect on what I see happening. What do you see differently about each picture? Describe what you learned.

Use-Your-Digital-Camera's-ISO-Setting-Step-1

Process:

  • Set the camera mode dial to Av (aperture priority) and use a 55mm focal length.
  • Go to a relatively bright location and photograph a subject close up. A location outside will work well.
  • Adjust the camera ISO from 100 to 6400.
  • Import your pictures using Adobe Lightroom and add them to your visual journal. Describe what you see different about each picture. Zoom in to each picture with Lightroom. Which picture has the least amount of noise? The most image noise? Do the colors and contrast of the images look the same?

Turn in your visual journal link to the Google classroom assignment Exposure Triangle at the end of the period. Remember to publish your work and view it before copying your link. You will be graded on the completeness of your Exposure Triangle research and how many Exposure Triangle assignments you completed and published to your visual journal.

Exposure Triangle – ISO

Questions: What differences do you see between the foreground and background of your photographs when shooting a picture at at f/5.6 versus f/22?

What do photographers call this effect created by adjusting the aperture?

Before continuing let’s review how to work with Lightroom and WordPress and cover basic use and buttons of a DSLR camera.

Learning Target:

  • I can adjust the ISO control of a DSLR camera and make five photographs using five different ISO settings.
  • I can post my pictures to my visual journal and reflect on what I see happening. What do you see differently about each picture? Describe what you learned.

Process:

  • Set the camera mode dial to Av (aperture priority) and use a 55mm focal length.
  • Go to a relatively bright location and photograph a subject (like flowers) with a consistent background. Use rule of thirds! Outside should work well.
  • Adjust the camera ISO from 100 to 3200 using a consistent subject, like flowers.
  • Import your pictures using Adobe Lightroom and add them to your visual journal. Describe what you see different about each picture. Zoom in to each picture with Lightroom. Which picture has the least amount of noise? The most image noise? Do the colors and contrast of the images look the same?

Turn in your visual journal link to the Google classroom assignment Exposure Triangle at the end of the period. Remember to publish your work and view it before copying your link. You will be graded on the completeness of your Exposure Triangle research and how many Exposure Triangle assignments you completed during the week and published to your visual journal.

Exposure Triangle – Aperture

Questions: Describe the difference in each of your pictures when adjusting the shutter speed of your camera from 1/15th, 1/60th, 1/125, and 1/500th.

Did you achieve a proper exposure (too light too dark)? Good image sharpness?

Add four pictures to your visual journal showing a difference in each picture depending on the shutter speeds you selected.

Learning Target:

  • I can adjust the aperture control of a DSLR camera and make five photographs using five different aperture settings.
  • I can post my pictures to my visual journal and reflect on what I see happening with the different aperture settings. Describe what you learned.

aperture-sequence-2

Process:

  • Set the camera mode dial to Av (aperture priority) and use a 55mm focal length.
  • Go to a relatively bright location and photograph a subject (like flowers) with a consistent background. Use rule of thirds! Outside should work well.
  • Set the camera ISO to 400 or 800 depending on the amount of light available.
  • Take four pictures at four different aperture settings (f/5.6, f/8, f/11, f/16 and f/22)
  • Import your pictures using Adobe Lightroom and add them to your visual journal. Describe what you see. Which aperture setting provides the most depth of field? The least?

Exposure Triangle – Shutter Speed

Learning Target:

  • I can adjust the shutter control of a DSLR camera and make four photographs using four different shutter speeds.
  • I can post my pictures to my visual journal and reflect on what I see happening with different shutters speed setting and what I learned.

Process:

  • Set the camera mode dial to Tv (shutter priority)
  • Go to a relatively bright location with a neutral background (like a brick wall).
  • Set your Aperture to f/5.6
  • Adjust the camera ISO to get a proper exposure. Remember to watch the camera meter.
  • Take four pictures at four different shutter speeds (1/15th sec., 1/60th, 1/125th and 1/500th sec.) of your partner running or walking past you (see illustration above).
  • Import your pictures using Adobe Lightroom to a new folder named Exposure Triangle Shutter Speed on your computer F drive. Add your pictures to your visual journal. Describe what you see. Which shutter speed is best at stopping movement?

Photo Challenge – Exposure Triangle

Learning targets:

  • I can complete an Exposure Triangle pre-assessment
  • I can use my computer as a research tool to look up what an exposure triangle is and record my research finding at my visual journal. Show photographic examples.
  • I can test my knowledge about the exposure triangle using an exposure simulator.

Notes:

You will need to log in to your school district Google drive account to access the Google form.

Making sure your simulated pictures are not too dark or too light answer the questions using your visual journal:

What does it mean to have a proper exposure?

What is the minimum shutter speed you need to stop the moving propeller?

What shutter speed creates a sense of movement in the propeller?

What is the best f/stop to use to get maximum Depth of Field (the most sharpness in the foreground and background)?

What is the visual difference in image quality between ISO 100 and ISO 25600?

What does the acronym ISO mean?

What does the ISO control inside the camera when you adjust it?

Respond to the questions and show your exposure captures from the simulator using your visual journal by the end of class today please.
