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.
