For my use 1:2=2X or one full stop additional exposure. 1:1=4X or two full stops.
If you're looking at the orange numbers on the focusing ring, those are magnification not exposure compensation. Top row is WIth the ring and lower row is without the ring.
Another thing to realize is that at 1:1 the film will be the same distance from the optical center of the lens. ~the aperture as the subject distance from the center of the lens
There should be a small circle with a line through it on top of the camera. this indicates the actual film plane
