I see two primary advantages of fluid mounting. One is the 
elimination of Newton rings, which can be a problems with some films 
(TMAX-100 for example) even when scanning emulsion down on glass. 
Another is an increase in micro-contrast. It is  the increase in 
micro-contrast that appears to give more apparent sharpness.
