What is Frequency Separation?
Frequency separation helps make retouching a portrait easier in Photoshop. Frequency separation works because it allows you to separate the texture of an image from the tone and color. When retouching you can focus on just the texture or the skin beneath it.

It sounds quite complex but in practice it is quite simple. If you want to work with texture, choose the high frequency layer, if you want to work with skin choose the low frequency layer.
Getting Started with Frequency Separation
To get your image set up for frequency separation you will have to make 2 copies of your background layer. If you are not starting from the beginning, add a Stamp Visible layer over all layers by typing CTRL+ALT+OPTN+E. One of these copies will be for your low frequency (skin) and one will be for your high frequency (texture).
First apply a Gaussian Blur to the lower (low frequency) layer. Choose a radius that blurs out the skin texture, but don't go too far as to make the face unrecognizable.
Next choose your high frequency layer and go to Image, Apply Image. Here you will want to se the Layer: to the low frequency layer. For blending choose Subtract and for Scale:2, Offset:128. These will be your settings every time, no need to change them.
Now you should have one layer with a blur (low frequency) and a layer above it that looks mostly gray (high frequency). Select the high frequency layer and change the blending mode to "Linear Light".
Your image should now look identical to the image before you started the process.
Correcting Underlying Color
To correct the underlying color (skin) choose an area with the lasso tool. I suggest feathering the selection to make it look more realistic. Use Q for Quick Mask as a quick way to see what your selection looks like. After you have made your selection choose the low frequency (blurred) layer and apply a Gaussian Blur in the selection. Choose a radius high enough to blend the tones together.
Repeat this process over different areas of the portrait to smooth the skin tones. Because the texture is on a different layer, it should stay in tact during this entire process.
Correcting Texture
If you need to correct texture, we recommend waiting until after you do the tone. Select the high frequency layer and choose the Clone Stamp Tool. In the Clone Stamp Tool settings be sure to hit Sample: Current Layer. This will make sure you are just using the texture and not sampling anything else. Then on your high frequency layer sample good skin texture using ALT and then paint over "bad" skin texture. This will work very well for stray hairs, acne, wrinkles and other small blemishes.

you have just explained something that my lecturers failed to properly explain in 3 years within 15 minutes. you sir are an amazing teacher
-
I know this is 2014, so maybe I'm a little late, but let me say this: YOU ROCK. Been following your videos and seeing the youtube suggestions from your channel, and I'm amazed. This for instance, I was looking for frequency separation tutorials. I was confused/ worried because takes to long. But this method is so much better. You have such a way of explaining things, and turned them simple. I'm really blown away. Thank you. You really help me a lot.
-
Clear, concise, easy to follow with a friendly tone. One of the best teachers Youtube has on their roster. Thanks for your awesome videos Aaron.
-
Your videos are sharp, clear and light. Exactly what I needed, thank you, appreciated.
-
I've seen many of these freq. sep tutorials and this is by far the best. It's detailed but easy to understand. You're a born teacher!
-
Great tutorial , the only addition/suggestion I would add is instead of using lasso tool and gaussian blur. do this instead : alternative: 1. duplicate 'layer 0 copy' apply gaussian blur to the duplicate 2. add a layer mask to the duplicated 'layer 0 copy' that has the blur applied 3.fill the mask with black 4. paint back in the blurs as needed by painting white into the mask there's way more subtlety and control with this method because you can use the brushes instead of awkward lasso selections and you can easily change back if you feel you've added too much blur. hope that made sense

You're extremely proficient in explaining more advanced aspects of Photoshop. I like the way to stopped at 5:13 to sort of do a check that we're all at the right point. I also love the way you gave an explanation at the start of the video. Some YouTubers just jump right in with little context. They say it's skin retouching but don't explain the method at the start, so it feels like you are just blindly following along. I'll definitely try support this channel by subscribing on your website. Thank you!
-
Just when I think you can't get any more awesome, I go and watch another one of your tutorials (like this one) and you prove me wrong. The PSer in me truly hearts you.
-
This never made sense to me... Until now. Wow, thank you! And also, thank you so much for generously offering the action. I've been watching these tutorials every day for 2 weeks now. I'm hooked! I've never had so many PS techniques explained so CLEARLY and in a way that holds my attention. I finally feel like I'm making significant progress in developing my PS knowledge. You guys do excellent work and help out a ton of people. So much gratitude! Thanks!
-
I'm so amazed! You cannot stop learning about Photoshop, even after 4 years I feel I'm still a newbie when I bumped into some brilliant technique like this one :D THANK YOU!
-
This is genius. It's an better/advanced version of straight up cloning and healing, with separating colour and texture making things so much simpler. Thank you for teaching it so well.
-
I have heard of this before, and even attempted it, but this is the brass tacks version I needed to understand why I am doing what I am doing, and also dive in with flexibility right away. Amazing for ffree content, and concise, too. THANKS!
-
This is the best FS video on YouTube! Very easy to understand and execute.Thanks, Aaron Nace.
-
Frequency separation made easy. Thanks
-
Gotta love Frequency Separation when it's done right! 👍 👍 👍 Thank you for sharing!
-
I regularly come back to this video for a refresher if I haven't needed to retouch faces in a while. It blows me away every single time. I downloaded the action several years ago and it is my favorite one to use to retouch. If, like me, you have the action already and you don't need to build the layers and you are just coming back as a refresher, the part you probably want to watch should start at 6:10
-
You are a friggin genius. I made a photography playlist for tutorials and tips and all the videos in it so far are your videos. Lol. For real though you've gotten me so interested in compositing.
-
great ! brilliant !extraordinary
-
Thank you so much for this! Very well explained and easy to understand. I was able to get my first retouching done. Thank you! I also realized that duplicating the texture layer allowed me to make a slightly soft image seem a bit more in focus/ crisper with a bit of making to the eyes.
-
Hey Phlearn, I just want to personally thank u soooo much for teaching us this frequency separation technique. Now my corporate photos look perfect and so natural!
