Retouching images is a fact of life for photographers, especially those doing portrait work. It can be as little as tweaking color and cropping down, but soon it evolves into fixing blemishes, whitening teeth, then resculpting noses and completely changing the way a body looks. There's been an increasing backlash against heavily editing models, especially women in advertising, for presenting young women with unrealistic body types. Some countries in Europe have pushed forward with legislation to ban retouching all-together. The problem with this is how do you differentiate between tweaking image sharpness and removing most of someone's thighs? Or clearing up some stray hair in the face compared to dramatically altering their spine?
