Text of Aperture priority

  • 1.Welcome to Boot Camp!
    • Each month we will be covering basic lessons in photography such as camera settings, lighting, composition, etc

    • F-Stop

4.

  • F-Stophow much light is seen, how much the aperture is open

5. Aperture Priority Setting

  • You set the opening size depending on how much area you want in focus
  • Camera sets shutter speed based upon how much light is being let into camera

6. Aperture = F-stop

  • larger F-stop (i.e. 3.5)
  • ADVANTAGES
  • Decreaseddepth of field , i.e. image background is blurry
  • DISADVANTAGES
  • Too much light, i.e. higher shutter speed.

7. Aperture = F-stop

  • Smaller F-stop (i.e. 16)
  • ADVANTAGES
  • Increaseddepth of field , i.e. image background is not blurry
  • DISADVANTAGES
  • Needs more light, i.e. slower shutter speed.

8. F-STOP

  • HOW MUCH LIGHT IS SEEN
  • Sometimes known as aperture
  • Ranges from about 1.8 to 32
  • A higher number (i.e. 32) means less light is seen.
  • A lower number (i.e. 1.8) means more light is seen.

9. F-STOP

  • LOWER F-STOP (i.e. F1.8)
  • ADVANTAGES
  • Lets plenty of light in! Better to use in darker settings.
  • Less blurry since faster shutter speed may be needed to compensate for more light.
  • DISADVANTAGES
  • No depth of field, i.e.background of image likely out of focus.

10. Aperture Adjustments

  • Increasing the opening
  • (large aperture)
  • Increasing the opening lets in more light
  • Make adjustments to offset too much light
  • Increase shutter speed allowing less light to flow to sensor
  • Decrease ISO to allow for less light to register on the sensor
  • Allows less area to be in focus

11. Aperture Adjustments

  • Decreasing the opening
  • (small aperture)
  • Smaller f-stop allows less light in
  • Make adjustments to correct low light
  • Decrease shutter speed
  • Increase ISO to allow more light to be registered
  • Allows more area to be in focus

12. F-STOP IMPACT Large aperture Small aperture
