To the users of Photoshop software to elaborate on the high frequency image segmentation techniques.
At the beginning, I want to recommend to you----reduce the light and deepen the map, later found that there are many similar tutorials on the site, we are interested in the search for the article keyword "d&b", "hyperbola", "soft light layer" can be found, commercial-grade portrait of the latter are used in this way to repair.
Foreigners specifically called this method for the image of the frequency segmentation technology, its basic principle is the use of subtraction in the image of the calculation, will be a picture of high frequency and low frequency layer, on the low-frequency layer with linear plus high-frequency on the formation of a complete picture, for example:
And here the low-frequency and High-frequency resolution can be changed, the above figure low-frequency ambiguity is 10, we can adjust to 3, became:
It looks amazing, doesn't it? After dividing the layers, you can modify the detail on the high-frequency layer without damaging the original color (this is similar to the repair/repair tool), you can change the overall light color on the low-frequency layer without destroying the details, which means that we can use the ordinary brush to smear the skin of the character without losing it.
So in this way, we will never worry about the fool's skin, the face like the repair and touch the flour regiment, there is no need to further reduce the light to deepen the picture, a stroke of the details of the repair, greatly improve the rate of revision, of course, I would like to remind you how much this kind of revision will lose this image details. Especially low frequency layer modulus, the more details lost, to achieve the best attempt to effect, especially when the character close-up, should be used to deepen the reduction of light, practical applications, should combine both to achieve efficiency and effectiveness of the optimal. There is the high-frequency layer blurred or sharpen, low frequency layer blur or sharpen will produce its wonderful changes, specific we can explore.
Interested students can follow the steps to make their own action, in order to understand the basic principles of more detailed, not directly for the action download, easy to operate later:
Rename 123, either arbitrarily or without naming, in order not to conflict with other actions.
Duplicate two more layers
Select the second layer of Gaussian blur, the value of arbitrary, depending on the degree of segmentation.
Select third layer execution: image applied to image. Notice what's inside the red box in the dialog box.
Layers that are obtained after the image is applied
Finally, the layer style is set to linear light to complete.
If you don't make an action, it's enough to duplicate two layers. Action made good, the Gauss blur that step of the dialogue switch open, so in the execution of the action, each Gaussian blur the specific numerical value can be controlled, easy to control the high and low frequency of the segmentation.
Blur three degrees, divide the layer and decorate the face.
To decorate the shoulders and arms
Step seems to be a bit too simple, but it is so simple, using the eyedropper tool to draw color, with a common brush smear a few, the basic effect came out, of course, because the skill is not enough, I am here to introduce the basic knowledge and principles, concrete application or rely on everyone to practice to explore.
Last but not the same, this method of revision is mainly used to share the work of reducing the deepening of the light, improve the efficiency of the work, so if you have to reduce the light and deepen the mapping method, you can understand the image of this infringement, you may be able to repair the map with less effort, if you do not, you should learn from the beginning, or carefully embark on stray.
Well, the above information is small compiled to you photoshop this software users brought the detailed high and low frequency image segmentation techniques to share the entire content of the picture method, you see the users here, now you are very clear skills, then everyone now go to yourself to try it.
