Abstract: An image processing method and photobooth employing the method are disclosed which produce a composite image using a conventional chroma-key device. The subject in the photobooth is illuminated with low temperature light and is filmed before a backdrop of uniform saturated blue color to provide a foreground image to the chroma-key device. The chroma-key device compares the intensity of the blue color component for each pixel of the foreground image to a threshold intensity level and replaces those pixels of the foreground image that have a blue color component intensity greater than the threshold with a corresponding pixel of a pre-stored background image thereby producing a composite image. By illuminating the subject with low temperature light, the method decreases the intensity of most blue color components in the light reflected from the subject to a level below the threshold level used by the chroma-key device.
