The Perfect Eraser can be used to remove distracting elements and blemishes from your image. It uses a content-aware algorithm that replaces the pixels with a natural-looking result within the boundaries that are painted. Using the tool is easy: click on it in the Fix group’s Tool Options bar, and paint over the area you wish to remove. Make sure you cover the entire area. A red overlay appears where you paint. If the first attempt does not give you a perfect result, simply paint over it again and it will improve with each pass.
