I'm not offended, I didn't mean to come across that way. Hard to communicate on the web sometimes

Re: How do you make even gradient skin transition?

Here is a screen shot of how I copy and blur parts of the low frequency layer. All is eventually flattened again later.

Well, with spatial frequency separation we split the image into high frequency and low frequency information.
Now what a bandstop filter does is eliminate a certain frequency range from your image. However it doesn't just get rid of the high frequencies (like a low pass) or the low frequencies (like a high pass), but it will eliminate a middle range of frequencies that you can determine.

Now with that in mind, think a moment about what happens when you blur the low frequency information of a split image.
The low frequency information is further blurred, which means that the highest frequencies of the low pass get eliminated while the lower frequencies still remain. Now on top of that we still have the original high frequency information, so that is retained.
With the original high pass the upper limit for the frequency removal is determined, the amount of blur on the low frequency information will determine the lower limit for the bandstop.
That's why blurring the low frequency is the same as a bandstop :-).

I hope this is understandable to you :-)?


Now the huge disadvantage of using this method is that your upper limit is already predefined, so you can't change that.
To fix this and still profit from Siciliana's idea, I'd suggest to use the usual bandstop technique (IHP) and clip the layers to two Brightness/Contrast adj. layers.
One of them should be set to "Lighten", the other one to "Darken". That way you can still determine the blending and have the added flexibility of setting the upper and lower limits more freely.

Re: How do you make even gradient skin transition?

I like your idea, Jonas, about the lighten and darken IHP layers. Will have to play around with this further when I get back to my computer this evening. Can you tell me how this might compare to using the 'blend if' sliders on the layer style panel?

Well from adding B&C layers I am getting lost there. How clipped lighten can influence mine (let's say) IHP21.??

Thks Jonas and Siciliana, I like your idea. I have to play with this.

Re: How do you make even gradient skin transition?

Very nice effect Jonas with the bandstop clipped to B/C layers. Do you use this often or is this just something you made up for the purpose of this discussion? I was able to get interesting results using your suggestion in combination with luminosity masks. I'm too tired. Will post tomorrow.

Tom, I hate to say this but I liked your original better. The new one looks too obviously retouched and that angular line down the nose is too much for me. She looks a little too space-alien now. I also think it looks too obviously dodged or painted over. This is just my personal opinion but I think you went too far. It is easy to do... I know I have been guilty of this in my own attempts. You have managed a smoother tonal transition in the cheeks and forehead, but pull back on the reins.

I like to look at Amy Dresser's beauty retouch for inspiration. She has a way of making skin look very believable even when going for a surreal look.
