log10(2^16)=4.81

The catch is that this reflects only the theoretical maximum range that can
be represented in the 16-bit output of the scanner; it doesn't guarantee
that the scanner actually manages to extract that range from negatives or
slides.  It's rather like saying that if you have a digital speedometer on
your car with four digits, your car's maximum speed is 9999 miles per hour.
