Those pictures, Miss Sommerton, are not genuine; they are not at all what they pretend to be. The prints that you have seen are the results of the manipulation of two separate plates, one of the plates containing the group or the person photographed, and the other an instantaneous picture of the falls. If you look closely at one of those pictures you will see a little halo of light or dark around the person photographed. That, to an experienced photographer, shows the double printing. In fact, it is double dealing all round. The deluded victim of the camera imagines that the pictures he gets of the falls, with himself in the foreground, is really a picture of the falls taken at the time he is being photographed.
