Bullets

• Terminology
  • Focal length $f$
  • Field of view $fov$
  • Exposure
  • Shutter speed
  • Aperture $A$
  • F-stop $N = \frac{f}{A}$
  • Circle of confusion
  • Depth of field
• Field of view
  • Dolly zoom
  • Relate field of view to focal length $fov = 2 \arctan(\frac{h}{2f})$
• Exposure
  • Time * irradiance
  • F stop & shutter stop
• Thin lens approximation
  • Gaussian thin lens formula
    $\frac{1}{f} = \frac{1}{d_o} + \frac{1}{f_i}$
• Depth of field
  • Circle of confusion
• Light field
  • Digital refocusing
  • Resolution
    • Aperture plane resolution dependent on the number of pixels under each microlens
    • Microlens plane resolution dependent on the number of microlens
  • Sub-aperture image
    Represents an image taken with a pinhole camera at the location on the aperture plane
