I have installed 2 lights for the studio. One has my SB-600 on a stand with a umbrella and the other is the same except with my SB-900 flash. I have installed a puffer on the pop up flash on my D300 to restrict the flash coming off the camera. I also bought to hydraulic stools to use for the portraits. Need to work on the set up and alignment of the lights and how I can use the natural light form the window.
