To the users of Photoshop software to explain the detailed analysis of the high frequency grinding method.
Let's take a look at the original artwork and the effect comparison:
Forgive me what I do here is not very fine ha, this is also a piece of material on the internet can often see pictures:
First we copy the original Layer two layers:
Then the layer 1 Gaussian blur, the degree of ambiguity to the basic ability to distinguish the face of the silhouette (the value is not fixed, because the next step will restore the screen.) I'm using a 37 Gaussian blur here. The numerical setting is to be able to see the structure of light and shadow in a narrow position:
Then we perform the image-apply image for Layer 1 copy, which is set as follows:
What you need to notice here is the "layer" option in the application image, which selects the layer 1 that was previously executed over the blur, and the blending is subtracted instead. Scaling 2, compensating value 128. After clicking OK we change the blending mode of this layer to "linear light":
After the change, the entire image returns to the same state as the previous background layer, right? The next step is the operation phase: We rename the previously Gaussian Blur layer 1 to "shadow layer", while the layer 1 copy of the applied image is renamed to "Textured layer":
"Texture layer" above, we can use the pen to repair, imitation stamps, such as repairing acne printing freckles and other defects, you will find that no matter how you use ALT sampling, even if the high light part of the sample to repair the dark part, the texture of the skin is still intact; Of course, this is more extreme, Note here that the "current layer" should be selected, whether it's a stamp or a healing brush.
"Light layer" above we can use the Brush sample skin color range to redraw the face of light and shade, such as the pipette Select the color of the skin, and then go to the whole face again. And in the light of the same time, texture is not any change.
The image of the "Light and Shadow" and "texture" separately into two layers to adjust without interference, this is the essence of high frequency.
Well, the above information is small compiled to you photoshop this software users brought to the detailed high and low frequency grinding method to share the whole content of the in general, the high and low frequency grinding method is the image of the shape and color decomposition into high-frequency, low-frequency two layers, separate adjustment, Non-interference, The low-frequency layer is used to control the color and color of the image, and the adjustment does not affect the picture details. High frequency layer mainly control the details without changing the color, I hope that small part of the sharing can bring useful help.
