Final effect

1, a lot of ways to highlight, I use the color filter, parameters to see the picture.

2, a filter color can not be a lot of light, more than a few copies of color filter layer as shown.

2, the effect is satisfactory after the stamped layer, delete the following filter layer.

3, new mask with 10% transparent soft angle brush brush high light area, the purpose is to repair exposure.

4, zoom in to see if it is large color block comparison star.

5, look at the red channel, face, hand, mouth part of the problem is serious.

6, green channel relative red relatively better.

7, the blue channel is more obvious, because the skin color contains yellow and red, corresponds to the red and blue channel exactly. Blue is a yellow color, so it's in a channel.

8, now know the noise is serious, back to the layer stamped layer.

9, I deleted the Mask Eraser high light layer to save computational resources, and then copy the stamped layer, hide the top of the above, to the following Gaussian blur as shown.

10, this fuzzy layer is the low-frequency layer, above I introduced. The low-frequency layer is mainly color and excessive, which I think is not good. The stamp tool is decorated to make the color too natural as pictured.

11, display and select the top layer.

12, do the application of image, parameters such as figure, after the high-frequency layer.

13, to see the high-frequency layer of the channel, red a bit noisy.

14, green noise or less, the reason for the color of green content is less.

15, blue or more serious.

16, learned that the green channel is better, so copy the Green channel.

17, back to the layer. Create a new Black layer, all I do is to want a clean high-frequency layer, the original high-frequency layer in the red and blue channel is not clean.

18, load in the green Copy channel selection on the black layer with white fill.

19, with repair tools to repair high-frequency layer of the black place, because the high-frequency layer is kept in detail, I want only the pores and outline details, those black things are not what I want, so fixed off.

20, the high-frequency layer into linear light, such as the figure to see if it is much cleaner.

21, and then look at the red channel, clean it.

22, green as clean.

23, Blue is also OK.

Finally, the grinding software is used to finish the final effect.
