One of the banes of digital photographers who have to change lenses in less than ideal field conditions is the potential to collect dust on the sensor.  This dust turns to dark spots on your image and if you have a lot of images shot at the same time, you have a lot of spots to deal with.

In this tip, I'm going to show you a tip using a basic Lightroom function to find and clean spots on a single image and then remove the same spots in all the images shot at that event.
