Another .45 Luger Question...

With my limited knowledge of photography I would still conclude that unless both pistols were photographed with the same camera and lens from the same position and distance, no conclusions can be drawn. The focal length of the lens in relation to the film size plays a large part in the perspective of the object being photographed. A wide angle lens positions the rear node of the lens much closer to the film plane, and invites distortion if everything is not kept absolutely parallel and perpendicular. The reference given to the building is one of the best examples. As the camera and lens is moved away from perpendicular with the building, the more severe the angle of the building appears. If the camera position is moved to an elevation where it is then perpendicular with the building, the converging lines of the building which gives the appearance of the building standing at an angle goes away. As long as all lines go through the center of the lens the distortion is virtually non-existent, but as the lens is tilted either up or down the change in the angles become more apparent.
As I doubt the two known .45 Lugers will every come together to be photographed, we will probably just to have to live with our own theories.
