RE: filmscanners: Aliasing again, alas

[Bill Ross]

        AFAIK most film
        scanners use a single row of CCD elements moved across the film or with
        the film moved across the elements, rather than a grid CCD like in 
        a digital camera.  So your grid pattern diagram shows the areas 
        "seen" by the CCD elements, not a grid of actual CCD elements.  
        The net effect is the same,
        so it may not be worth confusing people with.
        
        Only pedants like me would point it out. ;)
        
One interesting aspect of the linear array vs. the grid
is that in the array, light can only 'bleed' in one 
dimension, i.e. to 2 neighboring pixels rather than 8.
