Smashing Magazine posted a great list of 70 beauty retouching tutorials for Photoshop. Anything from how to smooth out wrinkles and skin tone to how to change someone’s hair color. Many of them are video tutorials, so they are easy to follow along. They are also nicely organized by category to easily locate the problem area where you would like to improve your skills.
Beauty retouching is probably one of the most popular application areas in which Adobe Photoshop is used extensively. There are two simple reasons for that. First, Photoshop offers a variety of advanced tools to smooth out skin and hair, optimize body proportions and emphasize some beautiful details. And second, if you have some experience with Photoshop it is easy to learn the basics and quickly produce very impressive and beautiful results.
Of course, beauty-retouching is a quite deceptive art. The masters of Photoshop create illusions which are hard to tell apart — unless you have both a genuine photo and the final result in Photoshop and can directly compare them. In fact, every day we consume perfectly retouched stars and models online and offline which just look different in the real life.
Still, it is not the reason to avoid learning advanced Photoshop techniques for beauty-retouching and study examples of how it is done in practice. The list below presents both image-tutorials as well as video-tutorials. Most examples have a before-vs.-after-comparison and you can follow the modifications with Photoshop step-by-step.
