Tutorial #9.
How to go from this to this; 
Made with PS7, but should translate to other programs pretty easily.
-Make your base. Sharpen if you want, but I chose not to.
-Paste this and set to Soft Light.
-Duplicate your base and drag it to the top. Set to Soft Light.
-Duplicate that and Desaturate it.
-Paste this and set to Exclusion at 43%.
-Paste this and set to Colour Burn 33%.
-Paste this and set to Screen 20%.
-Duplicate the first Soft Light layer you made. Drag it to the top.
-Duplicate it again and Desaturate.
-Paste this and set to Colour Burn 38%.
-Duplicate the Desaturated Soft Light layer. Drag it to the top.
-Duplicate your blue Colour Burn and drag it to the top. Make the opacity 100%.
And that's it!
Other examples;

Hope that wasn't too hard.
I'd love to see feedback and what you get. (:
