2. Because the base map is a picture of naked women in Europe, in order to make the skin color of the synthesized characters more realistic, I first make a rough adjustment to the skin color of the characters in the base map compared with that in the surface map. Select the whole picture with the rectangular selection tool box, and adjust the color tone under the menu functions of image-adjustment-brightness/contrast, color balance, hue/saturation, etc., so that the skin colors of the people in the bottom and top images are roughly similar. 3. Use the lasso tool or other selection tools to select the head of the figure in the plan. In order to connect better, you can choose more points under your neck. 4. Then press ctrl+C to copy, click the bottom map with the mouse and press ctrl+V to paste, and move the avatar to be replaced (you can also drag it with the mobile tool). 5. Under the edit menu, select-Free transformation, and adjust the head angle and height-width ratio until it is appropriate. Then adjust the opacity of the lower right frame to 60-70%, and paste the head portrait at the corresponding position of the bottom map to make it completely coincide with the facial features of the people in the bottom map. 6. Then adjust the opacity to 100% and save the application. Compare the difference between the skin color of the avatar and the skin color of the body, and then adjust the tone. 7. Adjust the color balance? 8. Adjust hue/saturation? 9. After the tone adjustment is finished properly, wipe off the extra pasted parts with a rubber eraser. When wiping, you can adjust the pen tip size according to the size of the wiping area, and wipe patiently and carefully. You can't wipe too much or too little. If you wipe too much, you can choose to take a step back and wipe again in the edit menu. Because I am not good at sketching, in this picture, in order to avoid the complexity of the fusion between the edge of my hair hem and my body, I erased all the long hair from my shoulders and treated it into a shape that all floated backwards. 10. After wiping, there are still some marks and color incongruities at the junction of neck and shoulder. First, I use the imitation stamp tool to repair the remaining parts of the edge with the same color and pattern nearby, and then use the repair brush tool to repair the color difference at the junction. Of course, you can also use the deepening and lightening tools to repair it. 1 1, through repair, repair processing, remove all traces and inconsistencies. 12. Finally, look at the whole work as a whole to see if there are any imperfections, and if there are any, deal with them again. After careful operation and careful carving in each step of the synthesis process, a seamless, realistic and natural Ann synthesis map was born.
