Aperture Made Simple

Objectives:
- Fstop vs. Aperture
- The Way the Numbers Work
- Less Light vs. More Light
- Shallow DOF vs. Greater DOF
1) Fstop Vs. Aperture
Aperture = The Opening Formed by the Lens Blades
Fstop = The measurement of the Aperture
Fstop = The measurement of the Aperture
2) The Way the Numbers Work
Fstop number examples: F/1.4 F/8 F/22
Small Fstop (Number) = Bigger Aperture (Opening)
Large Fstop (Number) = Smaller Aperture (Opening)
*Think of it as a ranking system. #1 is the biggest ranking (opening) #22 is a much smaller ranking (opening).
3) Less Light Vs. More Light
The Aperture controls how much light is let in. A big opening lets in a lot of light, a small opening lets in less light.
In photography terms: A smaller fstop lets in more light and a larger fstop lets in less light.
Simple practical application: A bright lighting situation you'll need less light to properly expose your picture. If you're in a dark room, you'll want to let more light in to properly expose your picture.
4) Shallow DOF vs. Greater DOF
DOF = Depth of Field:
How much of the image is sharp and in focus.
Bigger Fstop/Smaller Aperture = More of the image sharp and in Focus
Smaller Fstop/Larger Aperture = Less of the Image in Focus
How much of the image is sharp and in focus.
Bigger Fstop/Smaller Aperture = More of the image sharp and in Focus
Smaller Fstop/Larger Aperture = Less of the Image in Focus
Simple Application:
Adjust your aperture when:
1. You need more or less light.
2. When you want more or less detail in focus.
