Re: Who loves the Diva?

Certainly color temperature is important to the look of a scene, and we may choose to warm a daylight key to a much lower Kelvin than the ambient & background lights. I don't think tungsten lights have a different character, just a different color temperature.

I'm not sure what you mean by tungsten bulb quality, unless you're speaking of keying with a naked Fresnel rather than a diffused soft light. Sometimes a hard source makes a perfect key; it just depends on the look you're after. A Fresnel with diffusion looks very much like a Kino with diffusion. With perfectly smooth diffusion in either case, it's the size of the aperture of the light source relative to the subject that determines the softness of the effect.

Shooting in the studio with all tungsten lights, I frequently put warming gel on the background where I'm suggesting interior lighting is playing against cool daylight. Of course we light in-studio "exterior" windows with HMI fixtures so the light will be bluer than the "interior" lights.

Good shooting!
