ABSTRACT:
A strobe apparatus having a light emitter which emits strobe light and a color temperature converter for varying a color temperature of the strobe light emitted from the light emitter. The apparatus includes a first color temperature detector for detecting a color temperature of the strobe light after being reflected from an object, a second color temperature detector for detecting a color temperature of ambient light reflected from the object, and a color temperature controller. The color temperature controller controls the color temperature of the strobe light detected by the first color temperature detector, so that the color temperature of the strobe light incident upon the object to be photographed is substantially identical to the color temperature of the ambient light detected by the second color temperature detector.
