Resize the blurred area

Once you see the blue border around the face blur, you can adjust its height and width. This can be useful if, for example, you only need to cover the eyes, or you don’t like the fact that the blurred area covers the hair and the ears, and not just the face.

Please note that, while editing, the borders of the blurred area look quite sharp. However, after downloading the images, you will notice that the borders have become more feathered and look more organic in the image.
