Prokudin-Gorskii took out an English patent for a camera that took 3
simultaneous images using two semi-transparent mirrors to split the
light coming into the camera, which had 3 lenses. This is described in J
S Friedman's 'History of Color Photography' (p54), and I think it is
more than likely that this method was used to make the portraits.
