Can't Figure This Out!!!

Woah there folks! Those radii aren't set in stone, they're just what worked here. It's going to depend on the image - each one is a little different.

Basically you try to find a point (radius setting) that divides the pores from the grunge, and another point that divides the grunge from the facial features.

In general, yes, a bigger image is going to need a higher radius.

I'm going to write the tutorial tomorrow (got a couple of beers in my head now ) but basically I do this:

- Run a high-pass and look for the point that the grunge doesn't appear any more but the pores are still intact: remember this number (~3px) and cancel the filter.
- Run a Gaussian blur and find the point that the grunge is blurred away but the face is still there: remember this number (~9px) and cancel the filter.
- Obs: For this to work well the second number should be about 3 times the first (I had used 3,3 and 10 before but doing this again it appears that maybe 3 and 9 would be even better choices);
- Now do the method described which uses the filters inverted, 9 for the high-pass, 3 for the blur.

Tomorrow I'll explain it better in the tutorial, OK?

Thanks Ro, you explained that pretty clearly, I have a much better understanding now of what details to pay attention to when eyeballing the filter preview.

Ro - this technique is awesome!! I owe you one man!!

Here's a skin correction I did in another forum using this technique among others:

megl, glad you liked it. That came out real nice.

Sometimes I'll lower the opacity a touch from the 50% mark, to leave just a hint of grunge. Otherwise the skin can end up looking too perfect!
But this is going to depend on what the image wil be used for.

(too perfect?)

ByRo, thank you very much So simple and elegant, amazing, I would say!

Yeah - we were trying to achieve really plastic looking skin, so I went a little more overboard than I normally would. Here's an even more extreme try:
