Exposure Triangle

By: Andi Olson

Aperture


  • The smaller your F-stop is the Larger Aperture you have, but you have a Shallow Depth of Field so you will have a smaller picture.
  • The larger your F-stop is the Smaller Aperture you have, then you will have a Greater Depth of Field which will make your picture cover a bigger area.
  • Large F-stop= Large opening, Shallow Depth of Field and smaller pictures.
  • Small F-stop= Small opening, Wider Depth of Field and covers a wider picture.
  • If you use a smaller F-stop you will have a brighter picture with the background blurred. If you use a larger F-stop you will have a darker picture with everything in focus.

Shutter Speed

Exposure time that allows light to the film.


  • Longer Shutter Speed= Longer Exposure= Blurred photo
  • Fast Shutter Speed= Shorter Exposure= Clear shot
  • The longest shutter speed you can use holding the camera is 1/60
  • Longer than 1/60 you will need a tripod
  • Use Fast Shutter Speed for sports
  • Short Shutter Speed= 1 object in focus, rest blurred

ISO

ISO is how sensitive a film was to light.

  • You want to use the lowest ISO possible
  • Low ISO= Dark
  • High ISO= Bright and grainy
  • Adjust ISO based on how lit the room is.
