I decided to have a go a cooking up an image from four different exposure of the same image in photomatix pro. I then took it over to Photoshop for some noise reduction, sharpening and levels adjustment.
This is the result.
Camera Nikon D700 with 16-35mm Nikon Lens. ISO 100, 30 second exposure, f/22.0, 16mm. Tripod Mounted.
