Author: Anonymous Source: China Tutorial Network Forum Author: jdqq

This tutorial mainly uses Photoshop to use the background difference to cleverly select the method to pick out the mm. Let us learn together.

Final renderings

1. Analyze the background and determine the better cutout method. Open the background material and analyze the background. The hair on the top of the head is very light. It is a good choice to use a filter to extract it. The background color of the head is simple. Use the channel to adjust the level and cutout. It comes out fast. Of course, it can also be extracted, but it is too troublesome to use an eraser to remove the stains after extraction.

The body parts have clear lines and a large contrast with the background, so it is efficient to use the quick selection tool. Of course, you can also use the pen tool, but dotting is too labor-intensive.

After the method is determined, press Ctrl+J twice to get layer 1 and a copy of layer 1. Create a new layer (Layer 2) above the background layer and fill it with blue as the inspection layer.

2. Use Filter-Extract on layer 1, force the foreground color (black), and extract the hair on the top of the head.

3. Open the inspection layer 2, check the effect, and use the eraser to remove the noise.

4. Select the header

Use the pen tool to select the head, enter the path, and load the selection.

5.. Return to the layer panel Ctrl+J to copy the head to get layer 3, then load layer 3 into the selection, select the copy of layer 1, Delete, cancel the selection, and get the body part.

6. Cut out the head

Close all layers except the head, select the head layer (layer 3) and zoom in, enter the channel, compare the three channels of red, green and blue to find the channel with the greatest contrast with the background, in this case the blue channel , copy the blue channel, then Ctrl+I to invert.

7. Color Levels

Ctrl+L adjusts the color levels, this is a delicate job. Since the hair on the top of the head has been picked out, it will not be considered here.

Adjust the white point until the hair strands are clear. Lowering the white point value can make the face whiter and reduce the area painted with the white brush in the next step, but white edges will appear on the edges of the hair. If the value is too large, the next step will be to paint a large area with a white brush, which is time-consuming. In this example, when the white point is greater than 160, there is no white edge at the edge of the hair. However, the values ​​should be different due to the different size and shape of the selected head. (The values ​​in the picture are for reference)

The size of the black point value is related to the residue of the background. (See points 9 and 10 for illustrations of the effect of white field size on hair edges)

The color level value needs to be adjusted repeatedly to achieve the best effect

8. Set the foreground color to white, use a brush to paint the head white, and load the selection.

9 Return to the layer panel, Ctrl+J to copy layer 4, open layer 2 (blue inspection layer) to view the effect.

10. Further check the cutout effect

In order to check whether there is a white edge on the hair edge, you can create a new layer on the blue inspection layer and fill it with black. Looking at the picture, when the white point is 200, there is no white at the edge of the hair, and the head has been cut out perfectly

11. However, when the white point is 140, obvious white edges appear on the edge of the hair. Therefore, you need to be careful and patient when adjusting the black and white field.

12. Cut out human body parts

Close the remaining layers, select the human body (copy of layer 1), use the Quick Selection Tool, a brush of appropriate size, move along the periphery of the human body, Delete to delete the background, use the Quick Selection Tool again to select the part pointed by the arrow, Delete to delete the remaining Background, cut out the human body.

13. The picture shows the preliminary effect after deleting the background

14. Light up the small eyes in front of all layers (except layer 3) to see that there are defects where the arrows point. This is because they have little contrast with the background color.

15. History brush repair

Opacity of layer 2 (blue inspection layer)Adjust the brightness to 40% to make the background layer visible. Use the history brush to paint the defects of the copy of layer 1, where the head and body join. Apply and repair

16. Rendering after repair. The two girls have been cut out perfectly.
