For anyone who is familiar with PS software, matting is essential. Today, let's take a look at the methods of PS matting.

Two pictures, one is a tree, and the other is a distant house. Now we need to dig out these trees and add them to the picture of the house to make a foreground. Observe that there are many, dense and chaotic leaves. In this case, it is definitely not feasible to dig the picture with a pen or lasso tool. Although the background color has a gradual change, it is still relatively close on the whole. At this time, you can use the magic wand tool to select the background and right click.

After filling the background with yellow, we can see that the trees have been cut out, but the edges are too stiff and the traces of the cut-out are too obvious, so we go back, first select the background, then reversely select the main body, that is, the trees to be cut out, and click the selection above to cover it;

Select the Adjust Edge Brush tool in the toolbar on the left, and use the left and right bracket keys on the keyboard to scale the brush diameter, smear the edges and gaps of all leaves, feather by .5 pixel, adjust the contrast to 1%, and move the edges by 1%;

Select the output mode of the newly created layer, and finally click OK in the lower right corner. Fill the background with yellow again, and then enlarge the leaves. You can find that the edges are not only cleaned but also much softer this time. Finally, move the cut trees to the background image and resize them. The best method of ps tree matting

channel matting

The first step is to find a material and open it.

in the second step, we enter the channel, and those who can't find the channel bar here can be found in the window of the menu bar.

in the third step, we look at the red, green and blue channels separately, and find that the contrast of the blue channel is stronger, and the contrast between the tree and the background is also larger, so we choose the blue channel, pull down the bottom and copy one layer. Of course, you can also click on each channel layer to get a feeling for yourself.

step four, for better effect, we press ctrl+m to adjust the curve, so that the black, gray and dark areas are darker and the white ones are whiter.

use the "finger" in the picture to adjust the light and shade by clicking the specified color of the picture

Step 5, click OK, and then we will return to the copied blue channel, press ctrl and add the thumbnail of the layer to form the selection area.

step 6, after the selection is formed, we click the RGB layer, return to the layer, and then ctrl+shift+i deselect the selection.

step 7, ctrl+j, copy the trees in the selection, and then turn off the small eyes of the original layer, which will have the following effects.

in the eighth step, we set the foreground color to another color, and then go back to the bottom background layer. Remember, it should be under the layer of the tree, and then alt+ Delete key fills in the foreground color.

in the ninth step, we find that the colors of numbers are not harmonious. We can consider adjusting the colors, that is, synthesizing. At this time, we find the image, adjust the hue/saturation and increase the saturation.

Step 1: After the hue/saturation is increased, I found that the color is still not so good. This time, we found the image, adjusted and balanced the color.

Step 12, is it much better to transfer here? Then we can change the background color. Use Photoshop channel mixer to cut the forest, PS fast cut the forest

Original image

Create an inversion adjustment layer, and the effect is shown as follows:

The inversion command can convert the brightness value of each pixel in the image into the opposite value of 256 levels of color value, thus creating a negative effect. From the effect of inversion, we can see that the sky and the raw material show a relatively consistent tone, the branches of the trees are white, and the tone of the branches and the background has been initially separated, which creates conditions for our next operation.

create a new channel mixer adjustment layer and check monochrome. Reduce the red in the channel and increase the green and blue in the output channel, thus further separating the tones of the sky and the forest.

add a tone adjustment layer to enhance the difference of tones, so that the dark color in the image becomes black and the light color becomes white.

press ALT+CTRL+~ to load the highlight selection and select the forest. Double-click the background layer to unlock it, and click the Add layer mask button. Then all the adjustment layers are hidden. The following effects are obtained.
