1. Aperture & Shutter Speed

2. STEP 1 - LEARN In this lesson, you will learn about using aperture and shutter speed while taking photos.

3. Size of the shutter hole Also called f-stop (example: f/3.5) Allows more or less light in Controls Depth of Field (Background Blur) APERTURE Image courtesy of suphakit73 / FreeDigitalPhotos.net

4. The larger the opening of the aperture, the smaller the number set on your camera. Setting your DSLR to the AV setting allows you to control aperture while the camera auto sets the others. Larger apertures (smaller numbers) allow for a smaller depth of field, limiting the objects in focus. APERTURE f/1.4 f/2 f/2.8 f/4 f/5.6

6. APERTURE This photo was taken with a small aperture. Parker Pamplin, Bryant High School [AR]

7. How long the shutter stays open Measured in 1/x of a second Faster: Stop Action (Sports), less light Slower: more light, blur The bigger the denominator, the faster the speed (ie: 1/1000 is much faster than 1/30) SHUTTER SPEED

8. This photo was taken with a slow shutter speed. Becca Guevera, Horizon High School [AZ]

9. SHUTTER SPEED This photo was taken with a fast shutter speed. Amanda Pankhurst, Amboy High School [IL]

10. Setting your camera to the TV mode allows you to control the shutter speed while the camera auto sets the other controls. SHUTTER SPEED

11. STEP 2 - PRACTICE By the end of class today, take two photos that demonstrate thought and understanding of aperture and shutter speed.

12. Photo 1: Change the aperture (f/stop) settings on the camera and take a photo that demonstrates shallow depth of field. Photo 2: Change the shutter speed (1/X) settings on the camera to capture a subject in action. Don’t forget to use photo composition techniques like Rule of Thirds, bird’s/worm’s-eye view, etc! PRACTICE: APERTURE & SHUTTER SPEED

13. STEP 3 - DO Over the course of the next week, take four photos, to be used in the yearbook, that demonstrate your understanding of aperture and shutter speed.

14. Photos 1 & 2: Each must demonstrate the use of aperture to make the Center of Visual Interest (CVI) stand out. Photos 3 & 4: Each photo must demonstrate the use of shutter speed to stop a subject in motion. Write down the aperture/shutter speed you used for each photo and create a caption for each that includes the setting. Submit your photos electronically using PowerPoint, Prezi or Google Slides.
