The Camera and Aperture

  • The Aperture is located in the camera lens and not in the camera body!!!!
________________________________________________________________________

This is what the camera lens looks like as you change your aperture

Cell phone Portrait Mode and Aperture

  • Why does Portrait mode on your cell phone look so different?
  • Portrait mode mimics the Low Aperture/ shallow depth-of-field effect of professional cameras.
  • This mode blurs the background to make the subject pop

What is aperture?

Aperture: 

  • Is the opening and closing of the camera lens
  • It is written with an f before the number to indicate what the aperture of the lens is at

 

Aperture Controls 2 Things

 1. The amount of LIGHT that the lens lets into the camera senor

Bigger the opening the MORE light gets in

Smaller the opening the LESS light gets in

 

2: The amount of Out of focus or Sharpness in a photo

Low F/Stop Aperture

    • Called Shallow Depth of Field

    • Low  f/stop number (usually f/5.6 or lower)

    • A section of the photo is in focus and the background is blurred

What  is Shallow Depth of Field good for?

                                                                                      Portraits  

                                                                     Isolation of an object

Low light situations

 

The photos below were shot with a low f/stop setting on the camera

   

 

 

HIGH  F/Stop APERTURE

  • Called Deep Focus
  • High f/stop number 
  • Most of the photo is in focus

What is Deep Focus good for?

Scenery or landscape

Large Group Photos

Documentary

 

Note: The photos below  (f/12 or higher). They have a Deep Focus

How do you control the Aperture on your camera?

Step 1:

  •  Turn the top dial to AV to put camera into Aperture Mode
  • You will control the Aperture settings and the camera will automatically control the shutter speed

Step 2

  • On the back of your camera you will see a F with a number after it
  • This is the Aperture ( f/stop) number your camera is set at

Step 3

  • To change the Aperture (f/stop) numbers on camera
    • Turn the dial at the top right of the camera
      • The f/ stop numbers on the back of the screen will change
