ABSTRACT:
A studio lighting device for supplying light having a selected color temperature to a subject, comprising: an electrically powered light source connected to receive operating power which establishes a voltage across the source, the source being operative to produce light having a color temperature which varies as a function of the voltage; a first reflecting mirror for reflecting light in a first wavelength range, the first mirror being disposed at a location for reflecting a quantity of light from the source to the subject; a second reflecting mirror for reflecting light in a second wavelength range which is different from the first wavelength range, the second mirror being disposed at a location for reflecting a quantity of light from the source to the subject; and means connected for displacing the second reflecting mirror relative to the first reflecting mirror in order to alter the ratio between the quantity of light reflected to the subject by the first mirror and the quantity of light reflected to the subject by the second mirror.
