Abstract

A method of illuminating a subject during photography is disclosed. The method includes illuminating a background lighting system during a first image capture, illuminating a subject lighting system during a second image capture, and illuminating the background lighting system during a third image capture. The time from the first image capture to the third image capture is less than about 100 milliseconds. Also disclosed is a method for generating a composite mask of a subject, including receiving the three images, determining any movements of the subject between the first and third images, estimating an intermediate position of the subject during the second image, and generating a composite mask at the estimated intermediate position.
