Photoshop!

Hi everyone! ::waves:: I see it's a bit quiet in here but I figured I'd try anyway.

I'm about to start on a Photoshop project for a friend, and I'd love some suggestions on an effect I'm trying to achieve. Basically, the friend wants a the final image to resemble a noir pulp novel cover.

Anyone have tips or ideas on creating that sort of flat, yet textured painted look on a photograph?

I'm not looking for a one click filter or anything, just some ideas to try out and experiment with. In the past I've had variable success with using layers of paint daubs and watercolor set on different blend modes. I'm probably guessing I'm going to want to try to pull outlines from the image and strengthen them as well.

Any ideas? :)
