While this is not a complete, step by step tutorial, it does give you a little insight into some of my typical creative workflow when working on postprocessing photos.  This image, which is a self-portrait, was merely an experiment with my new lights, trigger, with a bit of make-up thrown in the mix.

Above, is the final image.  I was using a single Genesis 400 light shot into an umbrella directly above the camera.  My D80 with nifty fifty was mounted on a tripod, firing the flash with a Genesis remote.  My wife applied the make-up (which freaked her out just a bit) and the rest was history.

Rather than post a before and after shot, which is a little boring, I opted to create a short video to show the steps involved in creating the image.  Enjoy!
