Aperture refers to the opening in a camera lens that controls how much light passes through. A larger aperture admits more light and results in a shallower depth of field, blurring the background. A smaller aperture admits less light and provides a greater depth of field with both foreground and background in focus. Apertures are measured in f-stops, with lower numbers like f/1.4 allowing more light than higher numbers like f/8. The aperture can be controlled in Aperture Priority and Manual modes to achieve the desired depth of field and exposure for different photographic situations and subjects.

1. Aperture By Addie Butler

2. What is aperture? Aperture is the opening in the lens that lets more or less light in by opening and closing

3. The bigger the aperture, the more light is allowed in while the smaller the aperture, the less light is allowed in.

4. Apertures are notated as f/stops

5. f/stop Common f/stops or aperture numbers are: 1.4, 2.8, 4, 5.6, 8, 11 , 16, 22, & 32

6. The smaller the f/stop the wider the opening f/1.4 is a wider aperture then f/8 and therefore will let in more light. Each whole aperture stop lets in twice as much light as the one before For example f/5.6 lets in twice as much light as f/8

7. Depth of Field Depth of Field is how much of the area in frond and behind the subject that is in focus

8. The wider the aperture, the narrower the depth of field which will give you a blurrier background
