Checking For Sensor Dust on your DSLR

I always seem to forget these steps so I am summarizing them here…

  1. Set focus on lens to infinity.
  2. Set aperature to smallest opening(largest # e.g. f/22)
  3. Set exposure compensation to +1 stop
  4. Take picture of a uniformly lit wall or the sky. Exposure may take a bit, but it does not really matter.
  5. Check images on pc.
