Check out this great series of beauty retouching Photoshop tutorial videos by Sean Armenta from Fstoppers. The tutorial is broken down into 4 parts, from start to finish. In part 1, Sean spent the entire time working on just removing the blemishes on the model’s face and body. Part 2 was pretty much dedicated on stray hairs – yes, the entire 8-minute video. Part 3 is on detail enhancement, which includes eyes, nose, lips, skin tone, etc. Part 4 is finishing touches with the minor details and highlights.
You’ll notice that there was no tutorial on lighting setup or things like that, as the image already came in with perfect lighting. Once you’re doing this professionally, you make sure your lighting is perfect on the shoot, so that you don’t have to deal with it in post. This might be a bit much for your day-to-day wedding or portrait photoshoots, but it’s the amount of work that takes to get your photos published on big magazines.
