The making of To play, step by step...

Extracted the doll from the source image and desaturated it.

I learned some things about art history while tryiing to find what cubism really is about.

Created a solid color background layer. Duplicated the desaturated doll 8 times and applied the treshold command each time with different values. Then selected the dark areas with the polygon lasso, reversed the selection and deleted the unwanted parts.

Filled the selected parts with a solid gray. Set layermode to multiply.

Here is the result with some layers in place.

And some more layers...

Added the doll below the other layers.

Added some layer styles...

Extracted a part from the sheet music.

Well, it's cubism, we need a guitar....

Added the text and the notes.

More background...

Decided the color was not needed.
