Aperture and the Relationship to Depth of Field

Aperture and the Relationship to Depth of Field. Lower f/stop = shorter depth of field. Aperture set at 4.5 f/stop. Aperture set at 5.6 f/stop. Aperture set at 7.1 f/stop. Higher f/stop = deeper depth of field. Aperture set at 9.0 f/stop. Aperture set at 11.0 f/stop.

  1. Aperture and the Relationship to Depth of Field

  2. Lower f/stop = shorter depth of field

  3. Aperture set at 4.5 f/stop

  4. Aperture set at 5.6 f/stop

  5. Aperture set at 7.1 f/stop

  6. Higher f/stop = deeper depth of field

  7. Aperture set at 9.0 f/stop

  8. Aperture set at 11.0 f/stop

  9. Aperture set at 14.0 f/stop

  10. Aperture set at 18.0 f/stop

  11. 18.0 f/stop 4.5 f/stop

  12. Aperture set at 3.5 f/stop

  13. Aperture set at 4.5.0 f/stop

  14. Aperture set at 5.6 f/stop

  15. Aperture set at 7.1 f/stop

  16. Aperture set at 9.0 f/stop

  17. Aperture set at 14.0 f/stop

  18. Aperture set at 18.0 f/stop

  19. Aperture set at 22.0 f/stop

  20. 3.5 f/stop 22.0 f/stop

  21. But why would I want blurred or non-blurred backgrounds?

  22. CREATIVE CONTROL!!

  23. Perhaps you want everything in focus…

  24. Like this…….

  25. ….or this.

  26. Or perhaps you want just your main subject in focus, and other things blurred.

  27. Like this…..

  28. Or this….. This blurred background is also referred to as “Bokeh.”

  29. So…..Low f/stop number equals short depth-of-field, which equals sharp focus on the main subject and blurred backgrounds.

  30. Large f/stop number equals long depth-of-field, which equals focus on all elements in the picture frame and limited or no blurriness.
