In Photoshop, there is a very practical function:
1,import the paint image, and change the layer into overlay;
2,turn the original image into grayscale, and apply to a filter: gaussian blur,and save as reference image;
3,return to the original image, and click on the girl layer, apply to a filter: distort-displace;
4,then a window will appear asking you to import the reference image;
5,then the paint will change according to the curves on the face, which makes it more real.
