Alan -- I understand that if the film is not at the focal length the image 
will be blurred.  But please explain why narrowing the slit reduces the blur. 
 The shutter speed is faster, but the f/stop remains the same, therefore the 
depth of field (if that's the correct term in this situation) should be the 
same.  I'm having trouble getting past this concept, so please help. -- Marty
