New to Polarr is the Spot removal tool. This is a useful tool for removing blemishes or objects from a photo.
In the Spot removal panel, you'll find both a Healing tool and Clone tool. Both work different to remove spots.
Use the Healing tool when you want the borrowed source to blend the color and textures surrounding it. The Clone tool, on the other hand, is great for when you want to borrow the exact same source.
