Treatment methods of portrait trimming and polishing:
Method 1: Gaussian fuzzy skin grinding method.
(1) Using Gaussian blur to process the picture, the defects can't be seen clearly;
(2) Use a history brush to smear parts other than facial spots, including facial features;
The advantage of this method is simple operation, but the disadvantage is that it is easy to apply plastic texture and lacks realism. If there are many spots, the fuzzy skin will be very black.
Method 2: Hyperbolic skin grinding method.
(1) Open the image, find the channel with more spots, drag it to the New button, and copy a layer.
(2) Select the copy channel and use Filter-Other-High Contrast Retention. The value in the palette is set to 10.0.
(3) Select the processed channel, menu bar-Image-Calculation, the above values do not need to be adjusted, the following mixing mode is changed to strong light, and the channel Alpha 1 is obtained after confirmation.
(4) Calculate 1-2 times, and you will get channel Alpha3. After observation, you will find that the spots are in great contrast with the skin, and the skin is white and the spots are black.
(5) Hold down the left mouse button of the Ctrl key and click the thumbnail of the Alpha3 channel to get the selection area with bright colors. Ctrl+Shift+I reverses the selection to get a spotted selection.
(6) Click the RGB channel to return to the RGB color mode, click the layer adjustment board to return to the layer list, click the curve command under the adjustment board to establish the curve adjustment layer, and the current selection will naturally be passed to the adjustment layer mask.
(7) Pushing up the curve through the attribute line adjustment panel can brighten the spots in the picture, but other dark parts in the picture will also brighten; Use a black softening pen to smear on the mask of other parts that do not need to be brightened.
(8) The three-key +E back cover printing layer continues to adjust the unprocessed points in the image. If there are still many spots, repeat step 1-8 and pay attention to the light and shadow details of the face.
