Sensor dust is a fact of life for those of us using a DSLR. It is important to use good lens changing techniques and clean your sensor (professionally if you are not sure how to do it) if it gets to the point where dust is causing a problem with your photos. To deal with problem dust that is already in your photos, Lightroom® has a wonderful tool in the Develop module. The Spot Removal tool has an option that greatly assists you in identifying dust. This Quick Tip shows you how to use it.
