Photographic Effects

  • • Focal Length
  • • Shorter means wider viewing angle
  • • Sensor size varies; use 35mm equivalent:
  • wide-angle is <43mm (e.g., 35mm)
  • telephoto is >43mm (e.g., 135mm)
  • • Depth-of-field
  • • Distance range that is in sharp focus
  • • Smaller focal length increases range
  • • Higher F/Stop increases range
