Hey Neil:

Is it possible that because of your style(which I think is terrific) this technique would serve no purpose?

respectfully,

Rey

I am not being negative in any way, just trying to learn where it would be invaluable as a method. As far as skin retouching goes, for my own work the bar is high, but it's just as high for some PS wizards here too, and photographers too.

The above post on digital ironing is a perfect example. Other methods to do that would be very long.

That is what I'm trying to find out, where it is the way to go from other users experiences.

That was my best shot: remove larger scale problems while leaving a fine cloth fabric pattern.

If that doesn't sell you then nothing will

IT does, see my other post. Excellent example, I like it already.

Lanega,

I have read this and many other posts on it.

I followed through the tutorials and have tried it.

There is all the technique described in many posts. Yet there is no detail as to what it does better or why exactly you would want to do this .

Yes you asked what it does better and what you need it for
and I answered that question.

It's just another way of doing things. And if done correctly it could speed up your workflow.

I do , so HP could speed up my workflow. In what areas is it best, well not yet resolved.
You don't need it for anything. Sorry but I'm trying to find out what it is best at. You're taking this too negatively . I already said I find the post and actions you posted a nice find. Valuable too.

Neil, give me some time to get some things together. I'm working like a madman these days so I have so little time. It may give you some ideas of where you can use it.

I did say more or less that there is the density differences in the HP layer. I also realize it was created with add or subtract depending on the bit depth.

If you're referring to me here, my comment wasn't meant to refer to how the 'High' layer(s) is / are created; rather how the image data is being constructed [think: CMYK vs. RGB].

The most important question , which I've asked many times, is show me some examples of what you need this particular method for, where it is superior or the only method to use over the way I currently do it, and have done so from the beginning for many many spreads and ads.

It seems the method is not hard to do, perhaps the underpinnings are out of the visual domain and quite technical.

It's not a technique (nor are the plethora of its derivatives) which should be seen as having any specific purpose(s).  Certainly, there are a few things which it excels at, but rather than trying to say that these techniques apply to A, B, and C exclusively, rather think of this in the same way that you consider the hundreds of uses for ChOps, Curves, alternate image modes (RGB, CMYK, HSL,...), etc.  Really and truly, when done correctly, it is a whole new way of considering your image data, and as such has uses only limited by your imaginative application [particularly the derivatives].

For Carlos -- this didn't come out of forensics.  Certainly, it's something that the self-appointed image forensics crowd should be paying attention to (as, at last check, most still believe that the PS HP filter to be infallible); but that's not why I first posted on the matter.  Rather it was intended to get to the point we're now approaching in terms of community understanding and next-step application of that knowledge.

I thought that was the reason you started, but apparently it's the other way around.

But I am only interested in this part anyway and glad you shared it with all of us!

To those of you that have downloaded this action:
I just realized I accidentally set the D&B Curve Adjustment layers blending mode to soft light instead of Normal.
So I fixed this in the action.
You could change it yourself or download the action again(Same link)

Your action has some flaws. it's not working, like invert adj layer?

I see, what version of photoshop are you using?
I made it in CS5 so that could be the problem.

Basically it's just a black layer mask.
So if you know how to change/edit actions you could tweak it so it would work for you.

And if you are willing to share your version I'll put it up in this thread.

Yes, what does it excel at precisely?

What was interesting to learn was following through your multi part blog ( it was you wasn't it?). It is enlightening to know more about the pass filters why and how they work.

For me it's not about thinking too much about all the possibilities of how to do things, but one of how to do it best. Most of the things I will ever want to do are the most boring things around, repetitive, mindless , but time consuming. If HP can speed up things all the better, if it can do skin retouching at the level I see as correct , same.

I would have thought for those who really do know what they are doing examples would be easy to show. The digital ironing is a perfect point. Fast , easy correction. Would it be applicable for the last Kenzo ads I did? I suppose I'd have to give it a try.

A few examples of what it excels at would be appreciated by many reading this I'm sure.


PS.  Some people offered some good uses and samples offline already.

No, it's not that easy to show what it does because you could get the same results using other techniques as well. If it was I would have posted some for you already.

Just showing the end result is not really saying anything.

Therefore you would have to make a video to SHOW how it could make a difference in workflow and control.

And slapping a clear video tutorial together takes a little longer

Yes a know how to make and fix action. The problem is not the version of PS it's the action problem. I'm using CS5. Action can work on a older version of adobe PS. and yes I thought also that you wanted to make a black layer mask for curves ADJ.
Cheers!
BTW why do you make on top of the HP layer a copy of it clipped to the layer below?

It looks like your Curves Adjustment layer is created without a layer mask. So it's trying to Invert a layer mask that is not there.

This is done so you don't have to work on the original HP-layer.
You can just use your healing brush on that clipped layer called HP Heal Layer.
If you make a mistake on that layer, you can just mask it out with the mask attached.

If that is not enough undoing, you could do the following
1. Mask your mistake out
2. Duplicate the original HP layer(CMD/CTRL+J)
3. Merge masked out HP Layer with duplicated HP Layer
4. Turn into clipping mask again (OPTION/ALT+Click between the two layers)
5. Set blending mode back to Normal again

This way you won't have to split your image again if you mess up the HP-Layer.

Anyone else having problems with this action?

Here is a step-by-step of what it is supposed to do:
1. Rename the Background layer to Original
2. Duplicate the BG layer 2 times.
3. Rename Original Copy to Low
4. Rename Original Copy 2 to High
5. Select Low layer
6. Make Low a Smart Object
7. Apply a Gausian Blur to Low
8. Select High layer
9. Apply Image
10. Set blending mode of High to Linear Light
11. Select both High and Low
12. Make a group
13. Rename group to Split
14. Select the High layer
15. Duplicate High
16. Make the Duplicate a clipping mask
17. Set blending mode of Duplicate to Normal
18. Rename Duplicate to HP Heal Layer
19. Add a layer Mask to HP Heal Layer
20. Create a new Curves Adjustment layer
http://www.lanengaretouch.com/modelmayhem/sharpen_details_curve.png
21. Clip Curves Adjustment layer to HP Heal Layer
22. Set blending mode of this Curves layer to Lighten.
23. Select the layer mask of the Curves and Invert it to Black
24. Rename this layer Sharpen Details

These are the steps for the Frequency separation. If you want you could add in the D&B layers/group like I did.

Make sure you have Add Mask By Default turned on

OP,

I played a bit with your action. It is very cool that healing the HF layer does not smear color.

But:

Something I find not really convenient: It seems cloning and healing must happen on different layers because healing can affect only current layer (HF heal layer) and cloning must be done just above the LF layer with "Current & Below" setting. Switching between those 2 layers and changing the setting is quite an overhead.

Maybe I am doing something not as it is supposed to be done. Any thoughts/tips about this?

You can automate that somewhat if you want to get into PS scripting and UI customization, though I've not met many who thought it was worth the learning curve.

Someday if enough people complain about it Adobe might allow single-layer sampling from a different layer (as an opt-in option - even those of us asking for it will annoy ourselves sometimes), but that day hasn't come yet.

I dont really get what you mean or what you are trying to do.
What are you trying to clone?

Also, photoshop has a shortcut for moving through layers
Alt/Option+Shift+[ = Move DOWN a layer
Alt/Option+Shift+] = Move UP a layer

I have mapped these two to buttons on my wacom tablet.

Lanenga, if you explained the reason for step 6, ie, converting the LP layer to a smart object, I missed it. If you would rather not reexplain why, please refer me to the post where you or someone else explained the purpose.

Also, Natalia mentioned something about not using the same radius for all sections of skin. If I read her correctly I think she said that you need  a different radius for different part of the skin when smoothing the LP layer. I know she stresses using different radii when using the IHP technique. Anyway, I tried duplicating the LP layer 3 times, applying a different GB radius to each layer(15, 19, and 23 for first and only experiment) and then attaching inverted masks with each. Depending on which part of the face and the tones, I would use whatever smoothed layer seemed appropriate. Cumbersome process and I am not really sure if I improved the technique. Anyway, just throwing that out there for your opinion.

Thanks all.

Step 6. The converting to Smart Object is done so that when you apply a Gaussian blur or a Surface Blur(or any filter) it will become a Smart Filter.

So once it's a Smart Filter, you will be able to change the blur value after the split is done. And mask out certain parts.

I noticed some liked doing it this way.

As I mentioned before, I don't like working on the LP that much for reasons Natalia also pointed out.

This is the reason I don't like working on the LP.
I prefer to use D&B to smooth skin. It might take a little longer, but I got pretty fast at it and I just like the results better.

Anything. Having only a Heal layer does not allow cloning of color unless you make a separate layer just above Low.

Example: Let's say you want to clone out a tattoo or a logo on cloth. How would you do it using the split layer set?

True, as it is/was not intended to be used that way.
Splitting your image in frequencies is just a small step in the retouch workflow.

George Anchev wrote:

I would first clone the tattoo or logo out and then do a frequency split on the image to reconstruct texture.

This frequency separation, is in no way meant as a one step workflow.

I often use it many times for many different areas.
Fix an area
Stamp image
Fix an area
Stamp image
etc.

All these areas can be masked.
If I made a mistake in an area I can just redo that area.

This is one of the reasons to why I created this action to speed up the process of splitting so you can do it over and over a lot faster smile

Ok, I understand smile

My workflow is a bit different and that's why the confusion. I do a stamp only if there is no way to be done in other way. I prefer adj. layers to the very end. It's more flexible and saves faster/smaller wink

Anyway - good work! Thanks for sharing.

Yes same here, but after I fixed the texture I don't need the control(and extra layers) anymore.

Here is what you average jo blow can do with it. I am a photographer who likes to try to make my photos look better than they are. Here is my example plis a lill D&B and a lill sharpening for both before and after...... and a lill level adjustment me thinks.
its not perfect and i accept that. My girlfriend hates it for some reason......

Photoshop's adjustment layers allow you to make any color or tonal correction without permanently changing your image. There is a catch, however. Adjustment layers affect the visible areas of any layer underneath. If you want to restrict the adjustment to a specific layer or area you will have to mask it, group it with the layer you want to effect and change the blend mode of the group from pass trough to normal or you can clip the adjustment layer to the layer directly beneath it.

You can clip adjustment layers, normal layers, text, vectors etc. You can do that by using feature that is generally known as clipping mask. Here is some more detailed info.

http://www.elated.com/articles/creating … ing-masks/
http://photoshopcontest.com/tutorials/2 … k-101.html

P.S.
I haven't been able to find any decent video tutorial that explains it well, but based on the info that I provided you should have a fair idea of how it works and how you might banifit from it.

I use adjustment layers all the time of course. Its the mention of clipping masks and clipping to an adjustment layer that i dont get. Ive done google searches of course but never found what i was looking for.

Ill study up on the 2 links you posted.

Please do. But I suggest the whole repertoire of applicable scenarios. Not just the image inside the text kind. Something covering everything from adjustment layers and smart objects to text and vector shapes.

You should also do the "knockout" tutorial to accompany it although I believe Deke McClelland and Russell Brown already made those.

The past two days there have been threads on how to describe frequency separation in a simple step by step way that would be easy to follow for everyone.

Angela Michelle Perez made a very clean and simple video that showed how to separate your image into 2 frequencies. A Low and a High frequency.

Watch Angela's video: Watch video
However her video contains a little flaw which is discussed here.

EDIT:
Angela made a new video: New video

Photons2Pixels came up with a nice solution to how to heal non-destructively on the High Pass layer.
Described here.

But his methods required for either switching between layers or not being able to clearly see what one is doing.
so I made some changes to his method. As described here.

And I created an action for this method. Which was tested by rey sison photography and can be downloaded here:Download frequency separation action.


This action will...
- separate your image in 2 frequencies. A Low and a High.
- It will then attach a clipping mask to the High Pass frequency to do the non-destructive healing on (Healing brush Sample mode set to Current Layer)
- it will add a clipped curves adjustment layer for some detail sharpening
- and it will create a Dodge and a Burn curves adjustment layer for some D&B-ing.

1. Download the Action
2. Load action in Photoshop
3. Select your layer you want to separate
4. Make sure you have Add Mask By Default turned on
http://www.trefbal.com/work/adjustments_add_mask_by_default.png
5. Run action
6. Select a blur amount for your Low/High pass
7. Set the Apply image settings as shown below

8bit settings:
http://trefbal.com/work/apply_image_8bit_settings.png

16bit settings:
http://trefbal.com/work/apply_image_16bit_settings.png

8. Have fun and enjoy!


And here is a step-by-step of what the action is supposed to do:
1. Rename the Background layer to Original
2. Duplicate the BG layer 2 times.
3. Rename Original Copy to Low
4. Rename Original Copy 2 to High
5. Select Low layer
6. Make Low a Smart Object
7. Apply a Gausian Blur to Low
8. Select High layer
9. Apply Image
10. Set blending mode of High to Linear Light
11. Select both High and Low
12. Make a group
13. Rename group to Split
14. Select the High layer
15. Duplicate High
16. Make the Duplicate a clipping mask
17. Set blending mode of Duplicate to Normal
18. Rename Duplicate to HP Heal Layer
19. Add a layer Mask to HP Heal Layer
20. Create a new Curves Adjustment layer

21. Clip Curves Adjustment layer to HP Heal Layer
22. Set blending mode of this Curves layer to Lighten.
23. Select the layer mask of the Curves and Invert it to Black
24. Rename this layer Sharpen Details


For a better understanding of what it is and what it could be used for, read the HighPass Sucks (+ solution) thread by SRB Photo

Ok but does this wok for CS5 too????? I want to try but keep screwing it up.

That part of "Add mask by default" is not in CS5.

Also, Natalia mentioned something about not using the same radius for all sections of skin. If I read her correctly I think she said that you need  a different radius for different part of the skin when smoothing the LP layer. I know she stresses using different radii when using the IHP technique. Anyway, I tried duplicating the LP layer 3 times, applying a different GB radius to each layer(15, 19, and 23 for first and only experiment) and then attaching inverted masks with each. Depending on which part of the face and the tones, I would use whatever smoothed layer seemed appropriate. Cumbersome process and I am not really sure if I improved the technique. Anyway, just throwing that out there for your opinion.

Thanks all.

Something similar is in the video I made about a year ago. The way I (used to) do it is to separate initially at the lowest radius I'll need for a particular area. If any areas require further separation, I lasso that area on the LF layer and copy-paste it to a new layer, run further blur on it, then invert a mask on it. I actually have an action do all but the lasso part.

If you use the whole layer for each area you're going to work on, your file sizes may become huge, memory usage might be eaten up, and Photoshop could start to get really sluggish. It's just a matter of preference, though. I just don't see the need to copy the whole layer just to work on an area that's actually less than 10% of the image.

Yes it is!

In the the Adjustments panel click on the little icon with four horizontal lines and you will see the option; "Add mask by default".
