The "right" way would be with the shutter name at the bottom. This often results in the aperture and speed scales being at the top, which means you can't see them when the camera is on a tall tripod. I always mount lenses so that the scales are on one side and clearly visible. Of course, with smaller lens panels, it's often a matter of finding an orientation where the adjusting levers don't foul on the front standard.
