This step-by-step editing walkthrough shows a number of DxO PhotoLab tools in action, principally the Local Adjustment tools, including the Graduated Filter and Control Point tools.
Repair tool (DxO)
The DxO PhotoLab Repair tool works by replacing an area you want to repair with a same-shaped nearby area containing 'source' pixels for covering up the object you want to remove. It's similar to the Spot Healing Brush in Lightroom and can be used to remove sensor spots or small unwanted objects or distractions from the scene.
