Retouching is an essential part of photography today. In some ways, it's an art form in of itself. The idea of retouching can be debated, but the fact of the matter is, images that are taken straight out of camera can be so sharp that adjustments have to be made to create an aesthetically pleasing final image.
Standard retouching includes blemish removal, minimizing wrinkles (if needed), color correction, dodging and burning, skin softening, eye and teeth whitening.
Advanced retouching is eliminating/adding objects from the photo such as fly-away hairs, adjusting wrinkles in clothing, removing jewelery, etc.
