- In This video I explain how to properly use Frequency Separation and what settings are needed to preserve 100% of all information when using a 16 bit image. I also include and breakdown and compare the settings suggested and used by others - specifically for 8 bit images along with explanations of why you shouldn't.

I created my actions for frequency separation a while ago, saw your video, checked my apply image settings and sure enough I had the substract method for 16 bit. I fixed it and using the add method instead. Thanks learned something new today, even a small shift can cause issues
Awesome! Yes. I'm glad to hear that this helped. Thank you for sharing!
Dude! Such A good teacher! How the hell hasn't your channel blown up? Good stuff man
Hey! Thanks I’m glad you enjoyed it. Honestly I don’t put as much attention to this channel as I’d like to
Hi Steve.
My name is Jorge.
I am a Photographer and I live in the city of Rosario, in Argentina.
I want to congratulate you and thank you.
Congratulations on your way of explaining concepts that were very difficult for me to understand. This is, without a doubt, the best video I've seen (and I've seen many) on Frequency Separation.
You are an excellent teacher.
And I want to thank you for your generosity in sharing your knowledge. Today I discovered this channel and I already subscribe and I will study your videos.
Thank you so much!!! receive a cordial greeting from me. Jorge (George)
(My English is not very good and I use Google translate. Sorry! 😅)
Hey! Thank you so very much. I'm really happy to hear that.
@@SteveWalterPhoto Very Very excellent your video! Congratulations! 👏👏👏
Steve, This was THE BEST explication I have seen. Thank you.
Brett Haddock you’re very welcome! I’m glad it was helpful
agreed. by far.
Thank you so much for breaking this concept down for some of us new to photography. Like many others I saw videos on the topic but no one explained it as detailed as you did sir. Thanks a bunch.
You're very welcome. I really appreciate hearing that my thinking was helpful.
I have just been introduced to the concept of frequency separation today through other videos and I had no clue why the recommended settings were being recommended. Frankly, neither were some of the people making the videos (and understandably so because photographers are not "scientists!") I have to say as someone who is very into math, science, metrics, and just wanting to understand how things work, this video was EXACTLY the type of explanation I was hoping to find on why these values should be what they are. Thank you!!!
That's so great to hear! Awesome. Thank you. I too found that most didn't go over this stuff, that's why I made it.
Thanks for this steve, really insightfull and helpful
Awesome tutorial - clarified things that some other videos I've watched made confusing head-scratchers! Thanks for uploading
You're very welcome. I'm glad it was helpful. FS is a very technical thing and it takes a while to wrap your head around it. Sometimes the tech approach is good. Sometimes we need a simplification. Cheers
In the 3D world, High Frequency is like a Normal Map or Bump Map. Low Frequency is like Color map or Albedo Map
Yes! Totally. Very similar in concept. Great connection
Thank you so much for the explanation, finally i can understand this.
You’re very welcome! It’s a somewhat longer topic, but I’m glad you hung in there!
Hi Steve, Thanks for the great tutorial! I learnt a lot, God bless you man!
Thank you! Very much
You've this concept, very easy to be understood. Thanks.
This one of is the best Skin Retouching tutorial I have ever watched. Thankyou
Wow thanks!!
THANK U VERY PLENTY, I am very grateful.
Best tutorial I have seen on this subject
Ahhhhhh. Thank you! I greatly appreciate that.
Today I tried to figure out how to scientifically check if there is a shift that I can see. You saved my day! Thank you 😊
Been trying to understand this.. thanks
Man I finally understand how this works thank you so much these other videos don’t explain it right
Couchtalk1of1 Thrash awesome!! I’m glad to hear it’s helpful!
Dude! That's just the best!
Thanks for this video! I noticed that some frequency separation videos used the addidive method and some used the subtractive method. I wasn't sure whether it was a Mac versus PC thing or just six of one half dozen of another so this video answered my question. Just a thought from a viewer perspective. Towards the end when you were duplicating some steps maybe you could put the screen image back up; even if you're zooming through the steps I think it's more instructive to watch what's happening on your screen rather than just listening to you say what your doing; alternatively just do a jump edit and say I just repeated the steps I explained earlier in the video. But thanks again for this video and I hit the thumbs up and the Subscribe buttons!
Thank you. Glad it was helpful and I greatly appreciate the feedback .
great explanation, thanks!
Would have liked to see the technical explanation, where you incorporate the wavelengths...
Congrats! 1k subs!
YES! Thank you. It was like a nice birthday gift! HA
Loved that you mentioned preserving her birthmarks. I really don't like those plastic, robotic post that shows a person without any marks. It's boring, uninspired and kinda disrespectful with the subject.
Thank you Steve.
You're very welcome. I need to make a follow up on this actually showing the technique.
Great video ! thanks !
You bet!
Hello Stewe.
I watched Heart Oliver's frequency separation 2.0 video and I was wondering if it's possible to download the action he uses.
If so, could you tell me where to download it from?
Thank you very much.
Regards!
Finally I understand!
Yes! Awesome! I'm glad this was helpful.

Very clear explanation of a confusing subject.
Awesome! Very glad to hear. Thanks for the feedback.
Hey Steve question here after I remove the texture part apply the image won't show up for me any pointers?
for the first time someone technically explained fs
Yes! And even still, I don't FULLY understand the algorithm behind it all, BUT... I'm glad this was helpful.
Best tutorial
But, to apply image:
Scale and offset refused to change!!
What's the problem sir???
But I saw in another tutorials that u can use dust and scratch too
Can you create a matte painting??
Jateen Patil personally I never have. Are you talking about paintings used as composite backgrounds in movies?
is the intro a remix of girlfront by loona? lol
but hwat is a 16 bit image and how do you know does your camera tell you?
ZuluSango most cameras that capture a raw file actually capture a 14bit file. Slightly confusing, but when you open that raw file in photoshop it gets converted to either an 8bit or 16bit image. So, when it’s converted to a 16bit image, it’s still actually only 14 bit, inside a 16bit container. I hope that helps.
In Photoshop top left click on image then mode there it tells you what bit your working on! i always work on 16 bit because its better quality.
Great explanation - except - your video does not tell how to actually USE it. Your title should be How to Understand the Setup (only). Maybe I am missing some other subsequent post?
You're not missing anything. There are a lot of videos on the approach and technique. There wasn't any on the proper, use, method or setup. So, I can't deny that your point is valid. I suppose I should change the title. Thanks for your feedback!
You said you would explain why it should do it like that at 16 bit it should be done like that, but you didn't explain it! You simply said "because otherwise it is not precise".
What a great explanation. xD
Catapumblamblam - it’s short because it’s that simple. If you a want 100% accurate representation of the image after FS, use a 16bit image. If you use an 8bit image it’s going to be fine, really. BUT that is why I use a 16bit image. Thank for watching and I Hope that helps clarify.
@@SteveWalterPhoto hmm, maybe I didn't explain well. Why, technically, if we use 16 depth colors, this situation is changing? No others technics changes, but fs. I know, I already knew tha 16 bit need a different fs process and what is happening if I use the 8 bit process ina 16 bit image, but in would love to understand technically why.
It is not that if you repeat the same things 10 times, my question adapts to what you keep saying!
I said that if you say: "I'll explane why images with 16-bit color depth require that method to be 100% accurate" you should explain WHY the other method is not accurate and not just "because is lesser accurate".
See you
Catapumblamblam oh. Gotcha. It’s because a 16bit image has more color information. So in the deconstruction and then reconstruction of the image, it’s able to preserve it completely. The apply image function is very specific with this technique. The answer to that would have to come from Adobe. I’m just interpreting the process. Hope this technique helps in your workflow!
@@SteveWalterPhoto you are saying the same thing. I'll study myself technically why those more information require that method. Thank same
I don’t know what I’m doing wrong but no matter what my image is always altered even though it shouldn’t be. I’m going crazy trying to finish this image.
I’m not sure what might be happening, but even if it’s not exactly 100% - I think the image will still be ok. Most wouldn’t notice it if they weren’t looking for it.
when young the whole invert how come you don't just create a layer mask
lamarrion I’m not sure I follow your question exactly, but I do know this: there’s always more than one way to get the same results in photoshop. I’d always recommend using a workflow that works best for you. That’s the beauty of all this. You build on previous knowledge and workflows with new techniques. Hope this helps!
it's great, a little bit of a shift in color or buy a little bit powerful pc. It's your choice!
Manny Luna oh. Yea. Agreed. 16bit files are monsters and ram hogs. No question. 8 bit will work for probably 90% of everyone’s work. Mine included. This was just to show how to get it 💯, cheers.
A lot of noise signifying nothing. I neither understand or know how to use anything covered in this video.
my image for low turned white.......
Ooo. Not sure if what happened that would cause that. I’d suggest trying the steps again.
Like so many other presenters, you seem to think that you need a repetitive, i.e. irritating, sound track competing with your voice in order for voice to be heard.
Last few minutes of the video your face only has shown instead of the screen. why...
This music disturb...
Bummer
dude just use difference blend mode instead of useless check points bla bla bla
Hey! Thanks for the feedback. As I’m sure you’re familiar, there are multiple ways to achieve similar results in photoshop. Those markers in the case were, in fact, useful. Please do share a link to the video you’ve made using the difference blend mode. For sure I’d love to see it. Cheers!
Great info.
Super annoying and distracting music.
Sorry for what I am about to say ... nevertheless, I simply do not understand why in the world you took SO long to muscle through a complex "technique", that through my eyes ... made no difference to the completed edited image from the way it looked at the very beginning of the video.
What is the "fix" that was achieved? What was the "enhancement" that was achieved? What difference did all that work make, whether 8 bit OR 16 bit.
I've watched this twice through and see no reason for the effort. It appears that the image looks exactly the same when finished, as it did before anything was done. Similar to this comment.
@Jay Sigal Frequency separation is a means to an end, not the end result in itself. The difference is that once you've separated the color information from the texture information, you can edit the color of something in your photo without losing any of the texture, and you can edit or remove some texture without affecting the color.
Sorry, video is way too long and too much jargon. Tapped out
Thanks for the feedback. I really thought I kept my jargon to a minimum, It’s a somewhat complex topic so I wanted to cover the why and not just the how. There’s a bunch of other videos that talk about the how. And the comments in those videos ask why. So maybe I could try again with a happy medium of both.
@@SteveWalterPhoto Can't make everyone happy.
