What are the common f-stops used in photography and how do they affect the depth of field in an image?

Common f-stops in Photography include f/2.8, f/4, f/5.6, f/8, f/11, and f/16. Lower f-stops like f/2.8 create a shallow depth of field, blurring the background. Higher f-stops like f/16 create a deeper depth of field, keeping more of the image in focus.
