When it comes to touching up portraits, there can be a lot of work involved. Depending on the subject, there may be a considerable amount of things that need to be done in order to bring the image together. Painting in skin tones, adjusting makeup and hair imperfections, as well as removing entire objects from the scene are common problems. It’s important to have a well balanced understanding of how to use the tools in Photoshop to make your portraits look as good as they can.
