Kind moving of topic, but Mike since you mentioned it have also tried using the halogyn construction lights in my make shift studio, are you using filters to conter act the color casting, or shooting digitial and adjusting the white balance on a digital camera. I had found I am getting horrible casting. I was able to fix by shooting a macbeth color chart on the first and last frames, saving a color curve to correct and batch processing the role. but would be interested in what you do. jstuarj
