Yes, this one I learnt: http://www.modelmayhem.com/po.php?thread_id=439098

Pretty strange at the beginning, but after trying it many times and wondering how it works, it works

Oooo. I saw that thread the other day. I started reading and got a bit overwhelmed. I guess I'll have to give it another look.

Thanks

Oh yes, it gives headhache, indeed. But's quite easy at the end.

01) make 2 duplicates.
02) uncheck opacity on the very top layer.
03) select the second layer (the one in the middle).
04) apply blur (don't know how much).
05) turn back the opacity of the third layer (the one at the very top).
06) select the third layer
07) go to Apply Image. Select 'Add' in the blending, choose the layer that you blurred from the pulldown menu (it says Layer and 'merged' is selected by default).
08) put 2 in the 'scale' box and check the 'Invert' box
09) hit okay.
10) change the blending to Libnear Light in the layers palette.

Now your image should look like if nothing happened. That's correct.

Now you can start doing your editing. The very top layer is the texture (High Frequencies) and the one below is the Low Frequencies where you have the Light smoothed.

So you fix texture by using the HF and luminosity by using the LF. Very important to set the cloning tools to Current Layer instead All Layers or Current and Below in the tools palette (the upper bar in Photoshop where you change the opacity, flow, etc).

You can apply a lot of stuff in those 2 layers in order to fix the mess without messing with the texture

Wow, thanks for those instructions. For some reason it's not quite working for me though. I must be missing something. I'll read through the link on modelmayhem tonight and see if I can make sense of it.

Muy bad. I forgot to put that you should check the invert box in the apply image part. Now I fixed the steps (step 08 indeed).

=D

Re: My first attempt at High Pass

Ok, so I've been playing around with this for a couple hours now and at first I didn't understand the whole point of it. How was using the clone stamp tool on the high frequency layer any different than just using the healing brush tool? Then I started playing around and painting on the low frequency layer and it all made sense. This is really quite cool. I've been using photoshop for close to 12 years and I would have never figured this out on my own. And I'm pretty sure there is nothing in the manual about this either.

Re: My first attempt at High Pass

What would the difference be working on a highpass layer and a n blurred layer instead of the frequency separation layers. Seems to be the same thing to me.

I have yet to see one example of the benefits of frequency separation as opposed to the highpass and blur method.

Check the whites and the blacks (specially in details like catch lights)

This is just the reason why I didn't use to split the image because high pass sucked.

But apply image based HP is precise and can be used in a lot of ways.

This is the tutorial I was following

The main difference was I put a duplicate of the original layer back on top again and screened it back to 30% to bring back some of the imperfections in the skin.
I just tried to open this link and it said I don't have the right access :/
