Lens blur

An optical effect where objects outside the focal plane are rendered with reduced sharpness, simulating camera-settings. The aesthetic quality of this blur is termed bokeh.

Key Concepts

  • Depth of Field (DoF): The range of distance within an image that appears acceptably sharp.
  • Focal Plane: The specific plane where light is focused.
  • Physical Drivers: Blur intensity is primarily controlled via aperture, focal length, and subject distance.
