Recently i have been photoshopping my friends faces onto movie posters for the fun of it
My friend requested me to do this poster
Now i was wondering how i could get the shadows on the right sides of the faces if i were to paste in the faces of my friends...
and why do you want to do that? Do the pictures of your friends have the shadows on the right sides? It would be easier to transform and flip horizontal than to try to change the lighting on the poster. It doesn't effect only the faces. That is, if I understand what you want and I'm not sure I do.
