Depth of field (DOF) describes the area in focus, not the out of focus 
areas, lower numbers give a shallower DOF.  Also, in the real world, 
higher f/ numbers do not give a sharper image, in fact the reverse is 
true due to diffraction.

Two new suggestions?

description="F/stop ratio (lower numbers provide a shallow depth of field, while higher
numbers a deep depth of field)",

or

description="F/stop ratio (lower numbers help provide subject isolation, while with higher
numbers more of the scene will be in focus)",
