Explore the exciting new tools in the free beta of Adobe's Photoshop Lightroom 5
When dust gets on your sensor, it makes dots on your images. Removing them is easy, but sometimes spots you can hardly see on your display will show up when you print. Lightroom 5 can help you find and eliminate them. Choose Clone/Heal, and you’ll see a new menu item below your image. Check the box for Visualize Spots. Now the specks in the top-right corner of the image are much more clear. Use the Healing tool to remove them, and uncheck the Visualize Spots box to check your work.
