Step-by-step explanation:
The purpose of Photoshop's spot healing brush, healing brush, and clone stamp tools is to repair and enhance images. The spot healing brush is used to remove blemishes, spots, or unwanted objects from an image by blending pixels from the surrounding area. The healing brush also removes imperfections but allows you to specify the sampling source area, making it useful for more precise correction.
