sorry if the question had already been asked but how do you do something like this ?
thanks in advance :)
EDIT
I tried what they said but, it is not as beautiful or subtile as the picture above.
When I want to move my colored layer is not very precise. I want it to be just a little bit at the left, but it goes a little bit further. It's difficult to explain ... does anyone know how to fix this ?
here's my result, maybe it will help you visualize.
