"Normal" frequency separation or Wavelet decomposition

vojern · Oct 27, 2014

This weekend I found a plug-in for Gimp which provides a special form of frequency separation; see this article.

I find that it delivers more control than the "normal" frequency separation process, where only one texture layer and one color layer is used. I used a separation of 10 layers, which make it for instance possible to remove freckles in minutes. See the subtle change in this portrait:

PS1: for the "normal" frequency separation process I use this method for Paintshop Pro (X6)

PS2: I couldn't find an equivalent for the wavelet decomposition with Paintshop Pro. Although Gimp is easy to use, I wouldn't like to add another piece of software to my workflow if there is an alternative for Paintshop Pro.

Thank for the tip, never done this, but looks interesting and time to learn something new...

Thanks!

Hmm, interesting. I guess the key is the "grain merge" layer capability. If there is a way to simulate this, then Im sure you could create your own Wavelet script. Instead of having two layers, you could make several layers with varying degrees of gaussean blur?

It is likely more trouble than its worth. I might try downloading GIMP, just to get this feature in an easy to use way. Or, just try to figure out the two-frequency version of PSP...it looks like it gives pretty good results already.

A "Peano" tuit from ages ago. Adobe CS3 vintage. Duplicate layer/invert. High pass filter/Gaussian blur. Apply through black mask. Easy when you know how. Leaves the skin texture. Thank you Peano.

ACR for instance.

I'll grant it looks like the difference between Memorial Day and Labor Day.

Peano was the best! Also one of the most generous. I miss him both here and at Model Mayhem.

There is an action that uses frequency seperation but uses way more layers to edit.

Nah, that doesn't do it for me. The skin is waxed.

Sorry, looks like an overexposed photo now

That's interesting. I don't particularly want wavelet decomposition, I appreciate having more layers to work on. Thnx!

check your monitor settings.

It is lighter, but I said that in the caption, about a .35 plus on the exposure if I recall.

the rest of the apparent lightening probably comes from the reduced contrast.

aside from what I mentioned, there were no brightness or levels changes made.

Hi,

You can get Wavelets Decomposition for Photoshop in Fixel Detailizer 2 PS.

It really fast...

Here is a go at it. Anybody have suggestions.

Looks like it works well! Good to know

O I feel so bad...I did not use the wavelet tool. I simple did a bit of sharp - dodging - adjustment brush for shadows/highlights. Then PS the healing brush for the large blemishes. Then very gentle Port. Pro 12 with care not to make the skin waxy. U can still see some pores. This took about 15 mins max. Again, I'm sorry if anyone thought this was done with the wavelets exclusively. I saw that some other contributors had done some other retouching and I thought it was fair game. I will sit in the corner until tomorrow.

It doesn't look natural to me, Lyle. Bit plasticy.
