Filter, Film for Quartz Halogen Lighting I am thinking of using quartz halogen lighting for portraits. Is this a viable alternative? And, if so, what film to use? Would I need to us any special filters also?

The typical color temperature of a 150-watt quartz halogen lamp is at 3200K. Tungsten-balanced film would be the closest match to this color temperature. (Tungsten slide and print films are recognized with a "T" on the packaging.) You can also use daylight film with a blue 80-A filter. This will work fine for still-life subjects, but the light loss when using the filter will require longer shutter speeds ... which may present a problem for portraiture.

Thanks. What about 500-watts? Can the same film be used?

I do not like tungsten film. For product shooting, yes. To me it's like watching the movie '1984'...colorless. Just too white, unatural. I've never seen white tugnsten lighting. But I'm shooting interiors. My opion. Because your/my eyes do not see tungsten light as pure white. Which is why I do not like the white balance on my digital camera. You can use daylight negative film and correct it at proccessing. And also change it to black and white. I do have the 80A, B, & C filters...I mostly use the 80C in my interior work as the 80A tends to produce a slightly bluish cast. And all the colors with the 80C are exactly how you see it. Why do I use a filter on neg film? It creates a more accurate photo than the correction proccess. I do not know which of these filters will work best for portrait under 3200K lights. But I'm bet'n the 80B will give the best color skin tones. You do loose one stop of exposure. Yes, I had to buy all three used filters to test. Now I have an 80C Multi-coated B&W.
