Checking Sensor for Dust Spots

  1. Set camera to Aperture Mode
  2. ISO 100
  3. Manual Focus
  4. Highest Aperture Number on lens – F16 or larger number
  5. Photograph Monitor with a white screen (say blank word document) so that the monitor is out of focus, only dust will then be visible
  6. Examine image – preferably by importing into LR
