Sensor Dust

If you own a digital camera, chances are you have sensor dust. It gets in there somehow, and can make your life a living hell. You can spend a lot of time in Lightroom and/or Photoshop removing dust. but chances are you are missing lots of it.

Unless your aperture was set to f16.0 or higher changes are those dust bunnies are just blurry blobs that are hiding in the corners of your image. You need to use the following trick to find those guys and get them out of there.

The easiest way in Photoshop is to:

  1. Create a Curves adjustment layer
  2. Create a point at about 25% and drag it upwards towards the top.
  3. Create a point at about 75% and drag it downwards towards the bottom

Now look again and be amazed. All those dust bunnies, blemishes, loose hairs, scratches, etc. just pop right out at you.

When you are done editing simply drag that adjustment layer to the trash.
