Celebrity Face Swap with heavier brush strokes


Ok so what if the original isn't quite as realistic and has some visible brushstrokes? 

We'll be using these two sources, Jacques-Lois David's self portait and Chris Hemsworth whose face I could look at, and whose deep Aussie voice I could listen to, until the end of time and die a very happy woman. That tidbit of information however is not necessary for this tutorial.


As we've done before, copy Chris's face over the original, line up the eyes and mouth and reset the opacity to 100%


That hair really isn't working for me so using the clone stamp tool or content aware fill let's get rid of it.

The original painting is lit from the right, Chris has a very slight light on the opposite side, not enough to be a problem though so I've done a little dodge and burn work to adjust that.


The native Photoshop "artistic" filters can be fun to play around with, but they're not typically very good on their own for Ren images. But with a little tweaking they can be a good base, so let's go to Filter/ Filter Gallery and under the "artistic" group select "Watercolor". The settings I used are:
Brush Detail: all the way up to a max of 14, 
Shadow Intensity: 0
Texture: 1


And here's the result:


That definitely matches better but it's still not right, so using the smudge tool set at about 50% opacity try creating more of a brush stroke look to his face, like this:


There's a crosshatch kind of texture on the original painting. In order to make Chris's face match, select a portion of the background layer about the same size as his head and then copy/paste and drag it over his face layer. 
Now do a ctrl-alt-G to make the textured background bit a clipping mask.


As we did with the crackle texture above, completely desaturate the canvas layer so it's grey then change the blend mode to overlay and reduce the opacity to about 10%. This will give you that cross hatch texture over Chris's face. This is just a quick example, try playing more with the paint strokes to better match the original.
