This is really simple actually. Before tu get started, make sure tu have some textures.
Click Image ---> Adjustments ---> Treshold. mover a little cursor to increase/decrease visibility.
Click on your background image on the panel on the right and instead of normal choose screen,lighten o similar.
Before tu do that, tu need to unlock background layer. You're going to do that por double clicking little lock on the background layer. Then add textures.
