Two new options - Reduce Dust and Reduce Power Lines - are part of the Perfect Eraser in ON1 Photo RAW 2025. These one-click actions do what they suggest… automatically reduce and remove sensor dust spots and power lines from your images. Using the options are easy - just a click.
Remove Dust Spots
Sensor dust is a fact of photography - especially landscape photography! Even the most tried-and-true in the field lens swap techniques can’t protect sensors from all dust. The new Reduce Dust option in the ON1 Perfect Eraser speeds up the mundane task of clicking away sensor spots one by one. Click the button and let ON1 Photo RAW find and remove dust. The tools works quite well and will remove all but the most stubborn sensor spots. Even if Reduce Dust doesn’t get all the spots, it’ll get a lot of them and speed up your workflow.
Sensor dust is very obvious in the sky
With a click of Reduce Dust, most of the sensor spots in the sky are gone.
Remove Power Lines
Few to zero photographers like power lines cutting through your image. The Perfect Eraser has another new option, Reduce Power Lines. Click the button, let the software think for a minute, and power lines are removed from your photo.
The results for power lines cutting across a clear sky are excellent. However, power line removal does have its limits and can produce artifacts or false removals. Photos that have their own strong lines, like the siding in the church below, might be seen as unwanted lines and removed.
My guidance is to try the power line removal. If you see artifacts, decide whether those artifacts are correctable with other retouching tools, or if it’s easier to manually remove the power lines with a tool like the Generative Eraser.
Pro tip: After using Remove Power Lines, undo and redo the retouching a few times to check for artifacts in your photo.
Unattractive power lines cutting through the sky distract from the church.
Remove Power Lines in the ON1 Perfect Eraser removes the power lines with a click.
Conclusion
Reduce Dust is quite good and will streamline your photo editing. In most cases, it handles dust spots with ease and does not get too aggressive with corrections. You may have a few stubborn or hard-to-see spots to content with yourself.
Reduce Power Lines works well for power lines cutting through the sky. When power lines join buildings or power poles, there can be artifacts (and the poles will still remain!). Also, pay attention to areas of your photo where other lines get adjusted. Sometimes the software finds lines it thinks are power lines and applies corrections that you don’t want.
