Or 2) do the difference mode trick but without the threshold adjustment, so they will see the the black one expects from no discernible difference, or 3) keep the threshold adjustment layer but without the difference mode to show you've posterized the image to smithereens to get the effect.

All I can say is that people who are overly concerned with altering the content of an image to any degree probably shouldn't be in the retouching business, which is predicated on image alterations. It'd be like someone taking a flawlessly performed Doge and Burn job and pointing to a couple of spikes in the histogram and declaring that technique a failure on said grounds.
Exactly! This is art!

Of course every retouch looks altered when you know what the original is, of course it doesn't look scientific. It's not supposed to be a perfect representation of the person, but rather of a mood, of a feeling, emotion, passion, you know, like painting? Like music?

Only way it'll look like an original image is if you do nothing to it.

Re: Frequency Separation is evil

I've been using FS for changing the colors. I wonder why evil?

Re: Frequency Separation is evil

You'll need to either zoom in and crop as requested or since you're hosting offsite post much larger images for there to be any meaningful judgement.

Re: Frequency Separation is evil

This is a .CR2 file, full size, no resize, only cropped the face. It is SOOC, ACR 8.x was used, at default values, to decode the bits.

One is marked as "3", while the the other is marked as "C" - I did not want to use consecutive letters or numbers to avoid any preconceived ideas.

One is AS IS, the other is after the standard, run of the mill, 8 bit FS. No pixels were harmed in any way shape or form through out the process.

This guy gets the credit for supplying the source image: http://www.dpp.co.il/

Image C http://www.aiphotostudios.com/repro/C-test.jpg
Image 3 http://www.aiphotostudios.com/repro/3-test.jpg

Once Doug gives the OK, I will reveal which is which.

Happy holiday Mr. Janitor...I hope this meets your criteria.

Re: Frequency Separation is evil

No need to ID, as they are effectively identical. Good job.

Could you also post the individual separations?

Re: Frequency Separation is evil

How about the entire PSD file? 88.9 MB after the crop!

Let me know if there is any server issues.

Enjoy...

Re: Frequency Separation is evil

That is an excellent example, and it was kind of you to share.

If there is a chance these files will eventually go offline, I can host them locally with your permission. I think they'll be a valuable resource.

I'm looking forward to reading the opinions of others about these.

Re: Frequency Separation is evil

As long as I pay my monthly bill, they should be there - I actually have a folder called "repro" that should host everything related to Retouch Pro. However, If you wish, go right ahead, save them or host them somewhere, I don't own the source nor the FS technique.

For varieties of faces and textures to test on, go here for access to full CR2 files for a beauty session. He is a member of Model Mayhem, all he ask for is to be given credit if any of the images will be retouched and posted.

Click on the the thumbnail on the top to select which one to download.

I hope this helpful to all.

Re: Frequency Separation is evil

Doug, you threw down the gauntlet so play along here.

Lets take a hypothetical. Here's an image of wood I found searching for public domain images:

http://www.photos-public-domain.com/...od-texture.jpg

Let's pretend you're doing a catalog for a woodworker and he wants us to use this image but says the photograph is exaggerating the contrast and the blotchiness, so can we knock back the bleached areas a bit. Don't have to get rid of them but knock 'em back by 50% or so. The job doesn't pay great and you have 20 more images to do today to keep pace. Same or more coming in tomorrow.

Obviously, there's no time or need for Vogue level work, how you gonna knock it out in 15 mins? Shortcuts are the name of the game here, what's your method? Cloning is a possibility, but keep in mind you've got grain and cracks running in opposing directions, can't be too sloppy.

Clock is ticking...

Re: Frequency Separation is evil

Now you'll see why I have guest artists on RP LIVE, but selecting highlights as a layer mask and filling with a pattern made from a clean wood section didn't turn out too bad. I fiddled a bit with opacity and blur on the layer mask.

Once I remembered where the keys were it took about 5 minutes.
