How does one overcome the problem of film surface curvature caused by 
inserting the film in a frame while scanning - without taking the film 
out of the frame? The film has a natural curvature, and sometimes the 
rather stiff frames cause even more shape distortion. In fact, the same 
problem appears on the projector, too. The overall shift from the plane 
is less than 1mm, but we're talking about 3K-something dpi...
