This was an experiment in 'Painting with light'. My good friend Joe Carr http://www.joecarrphotography.com and I used flashlights to bring an otherwise completely dark scene to life by simply walking thru the scene and highlighting the areas we thought should be exposed, all the while the shutter is opened and exposing the sky. You have complete control in what elements you'd like to emphasize. It gives you the ability to really paint. We did use the tungsten feature of the camera white balance. A fun excersize to try.
